These are my new favorite shirts for outdoor activities, I've got one long sleeved and one in the short sleeve version. They're super stretchy and will move easily with you whatever you're doing. Put it on and do something rad. Take it off and rinse off in a stream. Wring it out, put it back on, and it'll be dry in 15 minutes. Repeat! The shirts have a nice soft feel to them. I'm 6' and 175 lbs and the larges are working well for me.

The fabric on this shirt is almost not-there it's so light and thin. It's perfect for sun protection on the warmest days, much better than slathering greasy sunscreen all over. I also recommend the long sleeve version.

This shirt is designed for rock climbing, but I have used it mainly as an around-town shirt. It's stylish and comfy. However, I can see its virtues as a climbing shirt: it's lightweight, stretchy, wicking, and even has a snap pocket. It's still early spring in the Adirondacks. If and when we get a warm day, I'll be eager to take it out on the crags.
