The North Face Modulator ABS
It’s known that larger objects stay near the top of an avalanche’s tumbling snow. So minimize your risk of burial with The North Face’s Modulator ABS, which isn’t a backpack in itself but rather a lightweight (4 lbs 9 oz) system that attaches to any two-strap backpack. Its two airbag pockets attach on either side of the pack using a harness and its trigger is affixed to either of the backpack’s shoulder straps for easy access in an emergency. And if you do pull it, a reliable argon-driven system fills two ultra-strong polyester airbags for balanced body positioning in a slide.
