Great for running
This is hands down the best lightweight running shirt I have ever used. I got it and ran a 50K in the desert two days later with temps in some canyons close to 90 degrees. I would normally use body glide or something but I didn't want to ruin a new shirt so I didn't and I had no issues with chafing even on the nips. Liked it so well I ordered another. The sleves are a little long but thats a good point when running in the open desert for hours on end.
