LIFESAVER
Should you get caught in a slide, the AvaLung-equipped Anarchist can improve your odds of survival. The device鈥攚hich is built into this comfy 1,953-cubic-inch pack鈥攔edirects the poisonous carbon dioxide you exhale, delaying the formation of a suffocating “ice mask” around your face. It reportedly can keep avy victims alive for more than an hour (sorry, our own testing only goes so far). 4.5 lbs; bdel.com
Bonus: The AvaLung II is sold separately ($130; 9 oz) for use with any pack.
Bummer: You need to ski with the tube near your mouth.
