Ortovox's thin WHITEOUT MASK provides effective protection for your face when things turn really nasty on the ascent or descent. This lightweight balaclava is made of 100% fine merino wool, which regulates temperature and moisture and feels comfortable on the skin. It will keep your face warm even in adverse conditions, and yet will fit under any helmet thanks to its lack of bulk. The large opening means goggles won’t steam up and the balaclava can be pulled down around the chin. The WHITEOUT MASK is small and light, yet extremely effective, and is absolutely essential in adverse weather conditions on the mountain.
