So this shirt is the $h!+ Felt great all day hiking and I never felt wet from sweat. Deff. not the case with some of my other shirts. Loved it so much I wish I only took one other shirt with me on my hike to change into at night. I literally wore this everyday, a quick dunk into a stream and it was as good as clean even with that fresh mountain stream smell like you can get with tide! Don't depend on this keeping you warm at all, it basically feels like you are wearing nothing except you don't end up with a sunburn.
