Saw the Apalain company exhibit on Orvis Fair in NY and later in a day, got online and bought Apalain shooting jersey. Got it a week ago and already wore it 3 times.
As a left shooter - the pads are on both sides and I am not sure what fabric they use but it is terrific.
It breaths, pads have a great recoil for being so thin, it looks fantastic and I am just sad I did not get the shirts they had on the Fair (and they are not online).
However, warm recommendation to get apalain shooting clothing.
