Great shirt, thought the $20 shirts were a bit pricey but its amazing. Worth every penny! Wear under body armor in 110 degree weather. Sure it's sweaty, but it keeps you cool compared to the alternative. The fabric rolls up under the shoulder straps when you first don the armor, but you pull out the collar and extra fabric from under the shoulder strap and it's pretty comfortable all day. Would get 5 stars but Wally World sells a decent shirt for $7.88. Let's see who lasts longer, shall we?
