Some days your excursions into the backcountry consist of one run, other times you're on a weeklong yurt trip. You always want to be equipped with an airbag backpack, but it doesn't make sense to have a different system for each size of pack your differing trips require. With the ABS Avalanche Rescue Systems Vario Silver Edition Complete system, you can purchase additional packs of various sizes to zip onto your one ABS base unit. The Vario Silver edition is lightweight and comfortable, well-suited for freeriders and hard-charging backcountry skiers. A neoprene hip belt and height-adjustable activation handle keep things comfortable for skiers of varying sizes, and the carbon cartridge keeps things light weight.
