Black Diamond Anarchist Avalung Pack

The Black Diamond Anarchist AvaLung Pack is the largest of Black Diamond winter packs and comes equipped with the added safety of an AvaLung. A fully featured top-loading backpack optimized for guides, snow pros and multi-day use in the backcountry. A-frame and diagonal ski carry options with fast and secure attachments. AvaLung system allows an avalanche victim to breathe fresh air directly from the snowpack via a bi-valve intake box located in the shoulder strap. AvaLung mouthpiece and tubing stow away in shoulder strap when not in use. Exhaled carbon dioxide is directed away from your body through an exhaust port on the pack's side. An AvaLung extends your air supply from the typical 15 minutes after burial to 58 minutes, especially important since average rescue time with beacons is 20 minutes.
