Designed for high-altitude mountaineering and filled with NASA-approved insulation, the Outdoor Research Tundra Aerogel balaclava is reliably warm, windproof and winter-ready.
- Trusted and tested by NASA, PrimaLoft® Aerogel insulation provides reliable warmth in cold conditions
- Polyester crown, windproof construction, and strategically placed Aerogel insulation add warmth where you're most susceptible to frostbite: your cheeks, nose and undereyes
- Over-the-mouth neoprene blocks wind while providing stretch and insulation
- Venting around the mouth allows condensation to escape so your goggles won't fog up
