prAna Snakebite

What a shirt. The cut is great - athletic fit but not painted on, so you can layer thin underneath it. Great as a base layer.

It is technical in design, with sleeves that compliment reach well. Plenty of length to keep you covered when you extend vertically. Supremely comfortable, with no chaffing (just as advertised). Breathes and wicks VERY well, and subdues the stinkies, although not as well as my Smartwool shirt.

Attractive style keeps me looking cool despite my awkward climbing skills.
