I bought a non-zip shirt, and the quarter zip version. I'm 6'4", 215 lbs, and the XL shirts fit great. I like the deep hoods, and the thumb holes are positioned well. I've worn these shirts for multiple days on a canoe camping trip, which included a lot of activity, and wearing them while swimming. I've worn them at the beach as well, including swimming in them. I haven't seen any rips or tears or loose threads.I also bought a couple of the Willit shirts in XL, and those weren't quite as nice. TSee full review
