Sheep skin! - Ortovox 185 Rock'N'Wool Long Sleeve - Men's

This is my go-to base layer, its warm, and I never seem to overheat in it. Its 100% merino wool so it wicks moisture well and does not stink after days of use. I have used this from skiing, and ice climbing, to mountaineering and hiking. High out-put, low-out-put this thing delivers! I am going on three seasons with this top, hundreds of days of use and its still in great shape.

I am a full time, year-round mountain guide and a member of the Ortovox North American team I received this gear to test and use.
