Our henleys were such a customer favorite, we decided to put them in our performance wear fabric. So you can look fancy, but won’t show pit sweat. Great for long runs. Or first dates. We have three types of crazy soft athletic fabric: lightweight, midweight, and heavyweight. This quarter zip is made with the midweight kind for durability and a quality we call not-sweating-through-your-sweater. Moisture-wicking, 4-way stretch, and mossed for extra softness makes this better than your average active(ish)wear. Colin is 6'1", wears a Medium, and in case you were jealous about how nice he looks in our tees....just know he puts them on in a really weird way. Sorry Colin, you know it's true.
