Rated 2 out of 5 by from Originally I loved these shirts. So much so that I bought two. The fit is perfect. Athletic but not too tight. Moves with you without being restrictive. Super comfortable. But... The smell. Oh my, the smell. They're supposedly made with Lava XL fabric to prevent odor build up. After the first few wears I noticed no scent. But now it seems like it's actually trapping the odor in there. I'll notice it a little when I first put it on but as soon as I start sweating it becomes unbearable.

Rated 5 out of 5 by from Cut right! I like the cut - I'm 6'0", 200lbs, and I didn't like the Co-op shirt because it was way to tight in the chest. The collar is a bit odd - it doesn't go all the way around. It's comfortable, but i think the lack of structure in the back means I've had to fidget with it more than other base layers when putting it under something.
