I bought 10 of these as just regular t-shirts/undershirts to use for everything since I go through clothes fast since I exercise every day of the week. I'm not a huge fan of the 100% polyester wicking stuff unless it's super hot in the summer because I have poor circulation in my hands/feet, and staying warm in other regions helps with this. The 60% cotton 40% polyester blend is the right amount of super soft but also not entirely 100% breathable, which I like. I REALLY like the fit on these, I am a 5'10 male that weighs about 160lbs with a muscular build. It stretches around my shoulder/tricep/bicep muscles the right amount and shows them off well in a size M (Medium). The v-neck isn't super low so it isn't showing off too much of my unsightly chest hair, which I appreciate lol.
