Look, you really shouldn't venture out into the backcountry on a red-light day anymore than you should practice your kite-flying in a thunderstorm or work on your backstroke in a shark tank. That said, yellow-light days are when the most accidents happen, and even a forecaster's green light is no guarantee of stability, so it's always wise to bring a few things with you. A working brain and finely tuned decision-making skills are the most important, but, along with a beacon, shovel, and probe, an avalanche airbag like the Silver Edition ABS Vario Base Unit can keep you alive if an accident does happen. As for the base unit itself, the Silver Edition has a narrower, more ergonomic design than the standard Vario base unit, and uses an elastic neoprene waist belt that's exceedingly light and comfortable. It doesn't carry weight as comfortably as the wider standard unit, so shouldn't be overloaded, but is an ideal companion for ski mountaineering and long tours where lightness and freedom of movement are paramount (And, it should be noted, the Silver Edition is perfectly compatible with all Vario covers.) The shoulder straps are ergonomically designed, the chest strap is height-adjustable, and the integrated leg strap helps your pack stay firmly on your back even in the turmoil of a slide. The Silver Edition uses the same deployment system as the standard ABS airbag packs: a trigger handle attaches to either shoulder strap, and uses a small pressurized capsule to trigger the main canister, inflating the airbags within three seconds of deployment. Once deployed, both the trigger capsule and main canister must be replaced by ABS or an authorized dealer, but the other parts of the system are fully reusable--simply fold up the airbags according to the instructions, pack them in the hook-and-loop side panels, screw on your new canister and trigger handle, and you're ready to ride. Please remember, an airbag system is NOT a guarantee that you will survive an avalanche;...
The Vario Base Unit with the ABS TwinBag airbag system attaches easily to different sizes of required ABS Zip-On pack bodies (sold separately) so you can choose the pack size that's right for you.
The ABS Vario Base Unit is a your life saving tool and a must have in the backcountry. This base unit of the ABS avalanche airbags is part of a proven system to prevent burial in an avalanche and to survive the fall with the fewest possible injuries. To avoid burial in an avalanche you have to increase your volume by a factor of 1.5 of your body weight. The inflated ABS airbags give an additional 170 liters providing the necessary buoyancy to stay on top of an avalanche.This unit does not include the activation unit or the canister.
