You wouldn't ski without a helmet, so why would you head into the backcountry without the protection of the Backcountry Access Float 42 Airbag Backpack' At 42L, it's big enough for long days or lightweight overnights, it has all the features you'd expect in a big time ski pack, and, most importantly, it comes with a quick deploying 150L airbag to help keep you safe in the event that you get caught in a slide. The trigger, which is height adjustable for easy deployment, attaches to either shoulder strap, so righties and lefties alike can activate their airbags in a jiffy, and the fixed leg strap ensures that the Float will stay attached your body, even in the turmoil of a slide. The compressed air canister is sold separately, but is refillable at BCA certified locations, so you won't have to order a new one every time. The Float 42 isn't a guarantee of safety you still need to educate yourself, make good decisions, and travel safely but an airbag is a proven backup when you're traveling in risky terrain. The Float 42 is more than just a portable airbag, though. It's fully hooked up with essential ski pack features like a diagonal ski carry, special shovelprobe pocket, and a dual ice axe carry system, along with a stowable helmet net, goggle pocket, and hydration ready sleeve. Daisy chains give you tons of lash points for extra gear, and the front panel access makes it easy to search through your gear and find the layer or snack that you're looking for. There are pockets on the hip belt for small gear like a compass and inclinometer, and compression straps on the side to lash down extra gear or cinch down your load so you can comfortable put the skin track behind you and start shredding that line you've been eying all winter.
