# Click here for snowboarding equipment This is the Black Diamond avalanche safety equipment "Avalung." Size is S/M (Small to Medium). Suitable for adult Japanese men. It allows breathing during snow burial by inhaling air through the mouthpiece and exhaling carbon dioxide from the back. It is useful as avalanche safety equipment for backcountry skiing, snowboarding, and mountaineering. I only carried it when backcountry skiing after purchasing it new. There are some scratches and minor marks from use, but it is in generally good condition. Please understand that this is a personal item and purchase accordingly. Please refrain from purchasing if you are overly concerned about condition.
