Early summer mountain pursuits can run the gamut between trail running and hiking to skiing the last remains of snow that still cling to the tops of peaks. With activities like this in mind, Patagonia designed its Men's Capilene Lightweight Crew Top. This lightweight baselayer can be worn on its own during cool weather runs and hikes, or layered under a midlayer when you strap the skis on to get a few June turns. Made with an eco friendly polyester, it wicks moisture, so you stay dry when you work up a sweat. A 35 UPF rating puts the stop on harmful UV rays, while a odor control treatment prevents any sour smells from taking hold after a couple of days of fun hogging.
