the is it
this is the end all be all of base layers. if i had to choose one piece of clothing to take anywhere, this would be it. it does it all, wicks like a mad man, dries before your eyes, makes the mountain man smell disappear keeps me warm into the 40's and can be warn virtually all summer long while peak bagging. i have warm just this while snowshoeing in the 40's and been perfectly comfortable, and i have had it on while hiking the virginia AT in June. buy it, you simply cant be disappointed. and i challenge you to not buy another as soon as you put on your first one.
