Black Diamond AvaLung II 2009: this device can truly be a lifesaver in an avalanche. The AvaLung II stands as one of the most significant breakthroughs in avalanche safety since the introduction of the beacon. Its purpose is simple yet crucial: it helps you breathe if you’re buried under snow.

This smart filtration system pulls oxygen directly from the surrounding snowpack. Even tightly packed avalanche debris contains roughly 50% air. With its specialized membrane that increases the breathable surface area, the AvaLung makes this air accessible. You breathe through the mouthpiece: fresh air is drawn in, while exhaled CO₂ is routed out the back, dispersing safely into the snow so it doesn’t contaminate your oxygen supply.

Designed for backcountry skiers, snowboarders, alpinists, and snowmobilers, the Black Diamond AvaLung is a must-have safety tool for anyone venturing into the mountains.
