The Wuru Wool Long Sleeve Nuyarn(R) is a great piece of clothing on its own. But it also makes a great layer for chilly mountain expeditions.

The result is a soft, impressive layer of warmth.

After spending a winter in this shirt, I was impressed by its thermal retention, odor-proof capabilities, and soft touch. And at a $69.95 price point, there are few long sleeve wool shirts that provide as much value for the cost. Whether I was spending the weekend at home, or headed to a multi-pitch climb in the mountains, this shirt was effortlessly comfortable.
