It was only a matter of time before the masters of building backpacks started including avalanche airbags in their ski packs. The Sopris is Osprey's premier, women-specific ski pack, and Alpride E1 is the leading electronic airbag in terms of lightness and reliability. Put the two together and you get Osprey's Sopris Pro Avy Airbag 30 Backpack. It's a combination of safety features in a backcountry-built backpack with women-specific sizing for a completely comfortable tour into backcountry terrain. The Alpride E1 can charge via two AA batteries in 40 minutes, or USB-rechargeable in 20 minutes. There are LED indicators to show when the system needs a recharge, and it's completely removable when you're skiing in avalanche-controlled terrain. It also has a compartment dedicated for avalanche gear like shovels and probes, and various carry systesm ready you for all sorts of tours, climbs, and day-long mountaineer routes.
