Look, up in the sky! It's a bird! It's a plane! No, it's just your hombre Randy taking it deep off a backcountry cliff with the ABS Powder Base Unit. Jealous' You should be, because Randy's way sicker than you, and he's also got the world's most trusted avalanche airbag system stuck to his back like glue. Weighing in at just over 5. 5lbs, the Powder Base Unit comes correct with heavy duty life saving chops, but doesn't hold you back, or down, with clunky design or extra pounds. More streamlined than most airbag packs, the Powder's narrow, compact shape is specifically designed for those looking for a small pack suitable for heli bumps, cat rides, or smaller, slimmer riders who want a pack that fits like a glove. With ergonomic shoulder straps, an elastic neoprene waist belt, and water repellent padded back panel, it'll ride more comfortably than should be possible, and, with an additional integrated leg strap, will stay firmly attached even if you do get spin cycled in an avalanche. The comfort, fit, and design of the Powder Base Unit are pretty awesome, but let's be real: its bread and butter is the time tested ABS TwinBag avalanche airbag system that deploys easily, filling two 85L airbags within seconds to keep you from ending up buried. All you need to do is choose which shoulder to mount the trigger handle on and make sure the included nitrogen filled steel canister is properly attached. For storage space, you'll also want to pick up an 8L, 15L or 26L cover that zips right on to the base unit. Also, please remember that an airbag system is NOT a guarantee that you will survive an avalanche get educated, get the right tools, travel with partners, and be smart out there.
