The bottom line is....Scent blocker or Scent lok is NOT 100% effective. But in order for it to be EFFECTIVE, you have to do it ALL. Yes I said that twice and it should be said twice because appearently not everyone understands it.

I agree 100% bud. I shower with scent eliminating soap before each hunt, use scent eliminating deodorant and scent spray everything I am wearing as an under layer for the day. When I get to my spot, I put on my Scent Lok suit and everything gets sprayed again, including, tree stand, arrows, bow, EVERYTHING. I also have the Scent Lok hat, face mask and gloves, and I wear knee high rubber boots.

I did the same routine prior to buying a Scent Lok suit and I was still getting nabbed by deer. Since buying the suit however, I have been winded exactly ZERO times. Whether my process eliminates every trace of human odor or just enough that deer aren't alarmed I truly can't say, but I have had mature and young deer down wind of me for LONG periods of time that never even so much as looked towards me with caution. And no, I wasn't in a tree stand every time either.

Do you need it to kill animals? No, but it's just one more tool that I will gladly keep in my arsenal.

I don't think that anyone disputes the fact that they work, it's the "how Long" do they work factor that's the issue here. For the money that those suits cost, and the longevity factor of the carbon to keep your scent at bay, it's not worth the investment to me. I'll continue to try to hunt the wind and keep myself and my clothes as scent free as I can.

Re: Scent lok

I've killed deer with scent blocker garments as well as the scent blocking technology found in Browning Garments. I've also used the old standard 3-d camo as well as regular camo to kill deer. All of these were used in conjuction with a scent elimination system such as sprays, soaps, shampoos, as well as towels and wash cloths washed in scent eliminating detergent. If a hunter wants to spend their money on these garments it's up to them but nothing can replace woodsmanship and practice with your equipment.

Oh yeah...the Wal-Mart where I live has sold scent blocker garments for at least the last five years. They had garments in the old MOBU pattern two years prior to the new MOBU pattern being brought out.

Since when did Walmart ever start caring the carbon activated clothing - Scent Blocker..?

I have yet to see Scent lok or Scent Blocker at our local walmart, they do not deal with either one... Nation wide every walmart sells the same items in particular, so i find it Ironic them carrying this particular clothing not to mention the "sale" you got on it.

Tell you guys what..I'm going back thursday,and I will get a digital pic of all the scent blocker clothing at my local store,and post it right here.$99 a pop just like last year,and then we'll see what excuses there are then.

A Response from Scent-Lok Technologies Scientific Experts

This article contains valuable information that helps refute the mis-information that has been circulated among several hunting web sites. In order to help educate and inform our customers, we asked our technical expert, Dr. Shulong Li of the Milliken Company that helps produce the Scent-Lok Climaflex fabric. Dr. Li holds a Phd. Degree and is one of the world’s foremost experts on carbon technology and textile applications. We have added Dr. Li’s comments in green to clarify the points that are in direct conflict with the author’s opinions.

llllllllllllllllllllllllllllllllllllllllllllllllllllllll

The extreme commercialization of bow hunting has, in my opinion, resulted instances where hunters have been duped. In fact, I can think of several products that are down right gimmicks and obviously seek to play upon consumer ignorance and slob hunters looking for success shortcuts.

I was once asked, “What do you think is the biggest gimmick on the (outdoors equipment) market is today?” I will warn you up front that my response to the question, which follows, may be a bit painful. Furthermore, I will say that if you do find my response painful, it’s likely that you spent your hard earned wages on the product that I’m about to scrutinize.

Here goes: I believe the biggest gimmick on the outdoors equipment market today is activated-carbon scent elimination clothing that are being marketed under various brand names. You know the ones I’m talking about, so I won’t name names. I’m talking about all of them.

If you’re a bow hunter and believe in the effectiveness of these special garments, hopefully you aren't so angry that you stop reading this article. Because if you read this in its entirety, I promise that you will learn something.

There is a difference between ignorance and stupidity, and I would never dream of calling my fellow bow hunters stupid. It’s the ignorance (i.e. the lack of knowledge) factor that has led many quality and even professional bow hunters to be fooled by the claims made by the manufacturers of scent elimination clothing.

I plan to educate you, not point fingers or spit propaganda. Before I do though, I’ll tell you a bit about myself. I am a biologist by education and received my Bachelor of Science degree from Florida State University. I’ve worked in the environmental protection field for more than ten years.

I have worked with various forms of activated-carbon, the same material that is used in the many brands of scent elimination clothing. Many of you have read articles by authors that claim their scent elimination clothing was pinnacle in helping them tag the biggest buck; without it, the hunt would not have been successful.

The author received a biologist bachelor degree from Florida State - that education background doesn't provide him any knowledge, not to mention expertise, to comment on activated carbon subject. His work experience with Environment Protection field is not clear to me regarding the connection to scientific knowledge on activated carbon.

What’s new? That is a common marketing strategy used to push new equipment. Bow hunters, despite what gear they choose, are a traditional bunch. Many of us have gained knowledge on how to hunt our query and what equipment to use through word of mouth and testimonials of other perceived more knowledgeable bow hunters.

When Chuck Adam, for instance, talks or writes, I listen and pay attention. I’d be crazy if I didn’t. He is without question a knowledgeable bow hunter and we all stand to learn a lot from an experienced bow hunter like him.

The problem with these scent elimination garments is, unless you have a science background and to an even greater extent, have worked in the environmental protection / remediation profession, you simply cannot posses a clear understanding of how activated-carbon works.

Activated carbon has many different applications beyond this biologist's knowledge. People who do academic studies on activated carbon, activated carbon manufacturers, and many different industries where activated carbon is used, understand activated carbon.

So, as I promised, I am going to tell you how activated-carbon works and why it is my opinion that activated-carbon scent elimination garments are ineffective. Then you can take the information presented here and make an educated decision for yourself.

activated-carbon comes in several forms and is used in many applications as a filtering or cleansing media. activated-carbon can be manufactured from carbonaceous material, including coal (bituminous, subbituminous, and lignite), peat, wood, or nutshells (i.e., coconut shells or walnut shells).

The manufacturing process consists of two phases: carbonization and activation. The carbonization process includes drying and then heating to separate by-products, including tars and other hydrocarbons, from the raw material, as well as to drive off any gases generated. Heating the material at 400–600°C (752-1472°F) in an oxygen-deficient atmosphere that cannot support combustion completes the carbonization process.

Activated-carbon comes in the form of a very fine powder, which is impregnated or weaved into the textile fibers of garments. It also comes in a granular form. Both forms are used in various applications including to purify both water and air. Some of the popular drinking water filters and mechanical air filters on the market use activated-carbon as a filter media.

".. which is impregnated in or weaved into textile fibers ..." Activated carbon can not be impregnated or weaved into textile fibers ( unless one melts a fiber and physically forces the activated carbon particle into a fiber melt - which is next to impossible in a textile process.) This person is certainly not knowledgeable in textiles or textile processing.

Activated-carbon is an extremely porous material with high ratios of surface area to unit weight. One pound of activated-carbon contains up to 100 acres of surface area!

Activated-carbon has a particular affinity to organic materials such as volatile organic compounds or VOC’s. Human odor is composed of different gaseous molecules of VOC’s and other chemicals such as hydrogen sulfides, which are absorbed by activated-carbon.

Think of activated-carbon as a common sponge that you would use to wash dishes with. Take a sponge and place it in a cup of water. What happens? It soaks up the water. The sponge, like activated-carbon, has thousands of little pores and channels running through it. When activated-carbon soaks up human “stink” odors, it does so through a process called adsorption.

"think of activated carbon as a common sponge that ....." It is not a right analogy. Activated carbon exhibits strong molecular force to adsorb and hold on to organic molecules such as those of different scents. The adsorbed molecules can not be easily removed or drained like a kitchen sponge. That is exactly why activated carbon can remove small amount of odor from air, not sending them back to the air if environment is still the same. Only when you heat up the carbon, pull vacuum, or purge with different gas or steam, activated carbon will start release the adsorbed molecules, depending the chemical nature of adsorbed molecules and the conditions.

Stinky gasses (i.e. human odors) are adsorbed into the many micro pores on and within the activated-carbon and are retained there. Now, what happens when a sponge becomes saturated?

A sponge that is saturated with water cannot adsorb any more. Hold a saturated sponge full of water in your hand and you will observe water dripping from it. When activated-carbon in a water or air filter becomes saturated it is called breakthrough.

In short, when a water’s or air filter’s filter media (i.e. activated-carbon) becomes saturated with contaminants, the filter is rendered useless and the contaminants contained in the water or air stream pass through the filter. After a while, you will be drinking dirty water or breathing stinky air until the filter is replaced. Makes sense right?

Think of activated-carbon as a molecular sponge. As is the case with any sponge, activated-carbon can only hold or adsorb so much stinky stuff. Once activated-carbon becomes saturated with contaminants, it must be reactivated or replaced entirely.

What do you do with a sponge that is saturated with water? You squeeze it to release the adsorbed water so you can reuse it. Or, you simply get a new dry sponge. Like the sponge analogy, activated-carbon must be “squeezed out” so to speak, in order to reactivate it for reuse.

Now you know how activated-carbon works. Most of the information I just provided can be found on some of the more popular scent elimination garment manufacturers’ web sites.

So far you might be thinking to yourself “Wow, activated-carbon really works”. Well, it does work, sort of.

activated-carbon is a fine filter media, but using activated-carbon as the key component in a scent elimination garment is not a practical application.

Unlike a common kitchen sponge, you can’t just leave it on the counter and let it dry out. In order to re-activate activated-carbon, it must undergo a process called Pyrolysis. To fully re-activate saturated activated-carbon, you must heat it to approximately 800 °C or 1,472 °F, in a controlled atmosphere of low oxygen concentration to reduce the possibility of combustion.

".., it must be reactivated ..." The author does not understand the differences between "reactivation" and "regeneration". Reactivated is to send activated carbon back through the "activation" process used in manufacturing activated carbon. It requires very high temperature as mentioned by the author. Regeneration, however, is a way of removing the adsorbed molecules on activated carbon, thereby regenerate the adsorption capacity without going through the "activation" process. On page 1030, of "Encylopedia of Chemical Technology" 4 Ed, vol. 4, there is one paragraph on activated carbon uses in solvent recovery, where adsorbed solvent is easily removed by pruging it with steam or heated nitrogen.

On the same page, under "Gasoline Emission Control" section, activated carbon is used to capture gasoline vapor, and activated carbon is regenerated simply by application of a vacuum. The temperature of steams or nitrogen gas used for regeneration vary from 100 C to 130 C.

In the Technical Notes of Rohm and Haas's Ambersorb, Carbonaceous Adsorbents, (Aug. 1992), page 6, “ activated carbon column demonstrated regeneration of activated carbon column with adsorbed chloroform, using 125-130 C steam, with 85 -90% contaminant removal. On page 7 of the same Note, under solvent regeneration, a regenerant solvent, methanol, or acetone is used to purge out adsorbed solvent, followed by rinsing in water or steam to remove any regenerant sovlent. As you can see, to regenerate the adsorption capacity of an activated carbon, you don't need to go through the "re-activation" process mentioned by the author of this article. In the case of Scent-lok, washing and drying in a home dryer certainly help remove some of the adsorbed materials, contaminants on the garment, and remove any odor source on the garment. The degree of regeneration depends on the chemical nature of adsorbed molecules, which varies with individual cases. I don't believe that we get 100% regeneration in washing and drying. It is, however, certainly a good practice to follow, and it will certainly help partially regenerate carbon and improve the adsorption capacity. (Copy of the references are in my lab if you need it.)

This is scientific fact and is even stated in the U.S. Army Corps of Engineers – Engineering and Design, Adsorption Design Guide, Design Guide No. DG1110-1-2, if you’d like to check it out for yourself. This fact is not however mentioned on any of the popular scent elimination clothing manufacturers’ websites.

One of the most popular scent elimination clothing manufactures instructs consumers to simply place worn garments in a common household clothes dryer for 20 to 30 minutes to re-active the carbon in the garment. The average temperature generated by a clothes dryer does not even come close to being able to generate the extreme temperatures necessary to drive out contaminants absorbed in the many micropores and channels of activated-carbon. In fact, most residential clothes dryers only heat up to a temperature that is well under 200°F.

Those of you, whom use water filters or air filters in your homes, think about it. Why can’t you just boil your filters in hot water or throw them in the oven or microwave for a few minutes to re-activate the carbon filter media. You can’t; that’s why. You don’t own special multi million-dollar pyrolysis thermal regeneration equipment that produces enough heat to re-activate carbon. Therefore, you have to buy new filters every now and then.

Re-activating carbon for industrial uses is big business. Type in the words “activated-carbon” in your favorite Internet search engine and you will see what I’m talking about here. In order to fully reactivate the activated-carbon in one of the many scent elimination garments on the market, you might as well just throw the garment in your campfire, because the extreme heat necessary to re-activate the carbon would likely destroy the garment anyway.

Forgive my sarcasm, but I tend to get irritated when I see good folks getting duped. And as a class, I think bow hunters are a pretty good bunch. So as a product, I think all the activated-carbon scent elimination clothing products on the market are nothing more than gimmicks.

I do not believe, based on sound science, these garments are even effective the first time you use it. Think about it. Each garment would have to be manufactured and placed in a sealed, scent proof bag when shipped and remain sealed on the shelf at retail stores. This is not the case, however.

From the minute the clothing is manufactured, it begins to adsorb “stink” and continues to adsorb “stink” while awaiting an ignorant, misinformed consumer to purchase it. It is likely that the activated-carbon contained in the garment is already completely saturated with “stink” upon being purchased.

"it is likely that the activated carbon contained in the garment is already completely saturated with "stink" when it is purchased." It is purely speculation with no scientific or factual support. If the garment doesn't get exposed to any environment containing enough concentration of "stink", how can the garment get saturated with "stink"?

In the same paragraph, military activated carbon suit is mentioned to be one time use only. First of all, I can imagine that Military application only needs to be one time use. Washing a garment contaminated with dangerous chemical weapon is certainly not a good idea. It is certainly not a good analogy to hunting garment regeneration.

Many of the scent proof garment manufacturers somewhat acknowledge this, in an attempt to bring some legitimacy to their product. They recommend that you immediately wash and re-activate garments by placing them in a clothes dryer as soon as the product is purchased. Funny, they also happen to recommend their own brand of laundry detergent that is special made for these special garments.

As I explained above, washing and drying the garment is merely an exercise in futility. At best, the only way these garments could be manufactured and utilized effectively would be if they were designed for one time use. In other words, they would have to be disposable.

The military actually uses activated-carbon suits as a kind of chemical protection garment, but they’re a single-use, disposable garment and not intended for multiple washings.

Here is something else you should consider before purchasing one of these products: activated-carbon’s adsorption effectiveness when used in an air filter application becomes greatly reduced when it is wet. So what happens when you sweat during those humid early season bow hunts? That’s right, your clothing gets wet and becomes even less effective.

A leading manufacturer of activated-carbon garments admits that no laboratory testing has been conducted to determine the effectiveness of the clothing when it is wet from hunter’s perspiration.

So why the craze? Why are so many hunters rushing out to purchase these garments, when the science-based fact is that they don’t work?

As I mentioned earlier, consumer ignorance is one reason. I think another reason is that many hunters so badly want to believe that they can purchase something that will render them invisible to a whitetail’s or elk’s nose.

As I said earlier, many of you have read articles by authors that claim their scent elimination clothing was pinnacle in helping them tag the biggest buck; with out it, the hunt would not have been successful. I truly believe the fact that these hunters who wore these garments while achieving success, can be chalked up to being merely a coincidence. Many of the authors who wrote these type articles failed to mention they were wearing their lucky hat and that their lucky rabbits foot was in their pocket at the time.

All sarcasm aside, I think many successful hunters who wear these special garments fail to recognize that they have been consciously paying closer attention to personal hygiene techniques before every hunt.

You must understand that none of the success story articles that push these special garments are based on science studies. They are opinions; misinformed ones at that.

I’ve talked to a few technical representatives with some of the more popular scent elimination clothing manufacturers and none of them have performed controlled scientific studies to demonstrate the true effectiveness of these garments. However, they claim to have “field tested” the garments. Come on folks. How do you field-test these garments?

It is said that a deer can smell nearly 1,000 times better than humans. You cannot legitimately observe the effectiveness of these garments or read a whitetail’s mind. No one, to the best of my knowledge, has contracted a non-biased independent laboratory or university to demonstrate the effectiveness or ineffectiveness of this clothing.

It is my belief that the manufacturers of these specialty garments know what the results of such a study would show; therefore it would not behoove them to undertake such an exercise. So they just claim the garments are field tested by the product-pushing pros.

As stated earlier: This is just my opinion, but it’s one based on sound science, education and a realistic view of product marketing techniques.

The author's ignorance of any scientific testing and data, doesn't constitute the product's lack of scientific proof.

Now you can form your own opinion. Good Hunting.

Note that the above comments were posted by some Scent-Lok Scientific Experts, who are "EMPLOYED" by Scent-Lok!!!! Geezzzeeee, maybe a little biased, No? Me personally, I'm inclined to believe the original article, that a dryer can't re-activate the clothes. What I'm saving by "NOT" buying these garments, I can pick up a new dozen arrows or other accessories for my bow.

To each his own, it's your money. wink.gif

Re: Scent lok

I got ScentLok outergarments for Christmas a year or so ago. I got close and shot deer without it and have been close to deer with it. I still use scent killing sprays too. I don't believe the ScentLok totally blocks human scent. I rather think of it as "toning down" human scent to levels that don't necessarily bother the deer because it's almost impossible to be in an area that is totally devoid of human scent unless you're in the absolute wilderness.

Hmm...those pictures look digitally enhanced. I bet you did some patchwork with your software at home...lol

This is too funny. Some people would argue that a stop sign is not red....

I'm really glad you found the items and the tags.

Congratulations on a great find..I'll be lurking around the hunting section in January...

Re: Scent lok

I just got a set of Scent Lock coveralls thru the Sportsmans Guide for $89.00. That is not much more money than a regular set of coveralls. Shop around if you really want the stuff..No need to pay top doller. Lots of guys swear by the stuff, others dont. I will wash them a few times during the season, and throw them in the dryer often. I think it will help some for sure. Maybe not alot, but you never know, a little is all it may take.......

Re: Scent lok

I don't remember reading anything in the directions of my Scent Blocker clothes about re-activating it in the dryer. It only said to put it in the dryer to remove the odors that had been absorbed.

If anyone does not believe that Scent Blocker or Scent Loc doesn't work try it on a blood hound and see if he can track you, that would be the ultimate test.

Re: Scent lok

Here is something to run through the old skull. If Scentblocker and Scent-Lok clothing is so great and helps you bag huge deer, why doesn't ever Tom, Dick, and Harry with a deer hunting show use the stuff? The only people you see using it are those people who have a show sponsored by it. You do a lot of people using the scent elimination sprays. I wonder how Chuck Adams was able to accomplish what he accomplished with out using Scentblocker or Sent-Lok clothing.

Re: Scent lok

i bought Scent blocker gloves at the Walmart in Des Moines last year.. they carry several jackets in Scent Blocker.. if you like im sure i can get a tag for you or pics from Walmart to prove this.. wink.gif

as for the Scent Loc post.. if a guy has the dough and wishes to buy Scent loc isnt it his choice ? is it any differant than a guy buy a grunt call or deer scent ?

i will tell you all that i purchased a Scent Loc jacket and pants 6 years ago.. i got the golves and hood also.. it set me back about 250 bucks and it was worth it to me.. i still have the jacket and pants and hood.. the gloves wore out , but the other stuff is in great shape..

my deer sightings went not only up , but quadrupled in number . and not just deer seen at a distance . im talking about deer within bow range , 35 yards and under..

i believe 3 years ago i passed up over 60 does and 30 bucks within bow range.. i used to keep these numbers , but i have gotten lax since it has gotten to be to many.

i have shot so many deer down wind that is not funny .. and when i put my scent loc suit on i feel like its a suit of armor.. i have had does and bucks come in downwind and scent check and i just laugh . dont even try it i say , its not going to work..

while i still watch the wind , i feel that its sometimes to hard to tell where the deer will come from...

i know that many of you feel its a gimmic and wont buy it. but i really do feel it works.. plus its just gives me confidenace , and when you have confidence in something you will hunt better .

Shoot Strong

Re: Scent lok

Tony you're right confidence is a big key to success.If it helps someone be more confident then I say use it.My friend has the military suit with charcoal in it.It is heavy,but he feels like he will see a deer everytime he uses it.I don't personally feel the need to use scentblocker,but for a reasonable price I will try it.Also in my original post I stated that I use carbon blast.I do believe it works,because I have had experience with it.I don't go without it.I have had better luck when I spray down with it.But it's a whole lot cheaper than a suit.
