Of 100 buried victims wearing a beacon, 50 will die. The Avalung significantly improves your chance of surviving an avalanche. When you are covered in a snowpack the exhaled air forms a cone around the mouth which prevents fresh oxygen from getting in. Once the mouthpiece is in place the Avalung functions as an artificial air-pocket, drawing O2 in from the surrounding snowpack and redirecting exhaled air to prevent CO2 contamination. Avalanche survivors have been buried for up to 45 minutes before being rescued safely. You do need to get the mouthpiece in place before being buried, but victims report having time to get it in when the slide begins. Available in harness style or integrated into a back pack. Couloir Magazine liked it so much they gave it their Design Innovation Award. Available from www.BackCountry.com.
