ColdAvenger Expedition Balaclava

Designed by a physician — and worn by high-altitude mountaineers as mighty as Ed Viesturs — the ColdAvenger Expedition Balaclava is in the running as the warmest head covering ever made. It protects you from cold, sun and wind.

The unique ventilator, a filter made of “medical-grade” plastic, fits over your mouth to mix inhaled cold air with exhaled warm air, keeping your body better regulated, the company says. $79.95, www.coldavenger.com
