This long sleeve shirt is so light weight and breathable. It's the perfect shirt for running or working. This shirt also has a great fit. It's loose enough to move around and not feel constricted but not baggy,

A great performance shirt and my favorite color green. Thanks for the quick shipping

I have no clue how Runyon has not blown up in the trail running world in Arizona. I originally fell in love with them for their logo. I run with a dog that looks like a coyote so kinda perfect fit for me. What I wasn't prepared for was the best running shirt I have found. It stays put with zero riding up. Wicks moisture so you never feel sweaty and gross. Does not smell even if you wear it three days in a row while running in the back country of Colorado. Knowing I am supporting a small business and American made is the icing on an already awesome cake.
