AvaLung II Black Diamond Device

The AvaLung II Safety System:

The AvaLung II is comprised of one-way valves that direct exhaled CO2 to the tip of the device, away from the inspiration zone.
The AvaLung II is designed to create an opportunity to breathe under the snow when a usable air pocket is not available.
This device can increase up to four times the reserve of usable air under the snow.

• Allows a person buried in an avalanche to breathe fresh air directly from the snowpack
• Bivalve-inspired housing extracts air from the surrounding snowpack
• Mouthpiece delivers fresh air through bivalve housing and exhausts CO2 through exhalation conduit
• Completely removable without tools for 4 season use
• very light: 265 g in size S/M
