The perfect compliment to our ultralight hoodless sleepingbags, such as The Arc-Alpinist, our down balaclava is unlike any sleeping bag hood you have ever used. Versatile in function in daytime and easily omitted form your sleeping system in warmer temperatures, the balaclava is simply warmer for the weight. A 5 snap closure in front makes breathing options at night easily adjusted, while our shock-cord and toggle face closure is soft against the face. Amazing warmth for a total of 4 ounces in Epic by Nextec, 3 in Pertex Microlight. We fill this down hat with 2+ ounces of 800+ fill power down.
