Honestly, this shirt was not at all I expected. When buying it, I was comparing it to the Run Barefoot Tee's, which are very light. I didn't realize this shirt is a double-knitted mesh (stated in description), which turned out to be stiffer than the RBT. However, this shirt rest real lightly on the body. It's very deceiving. When outdoors with this shirt, I feel my body gets hotter because of the double-knitted mesh, BUT oddly enough this wicks WAY better than my RBT. It's also extremely durable. After many washes and uses, this shirt still looks great unlike my RBT where the design is lightly fading. Very nice shirt. It's a little warmer than other shirts that I have, but as previously mentioned it wicks way better than any other shirt I own. This shirt doesn't stick to my body at all. It looks good, and feels good. Easy happy buy for me. This shirt is so durable, I'll be wearing it for quite a few years to come. Thank you Merrell!
