Here's what other sites are saying:
Prepare yourself for the ultimate backcountry emergency without feeling like you're lugging around the kitchen sink when you strap on the ABS Avalanche Rescue Devices' Powder Line 5 Backpack. This compact pack includes the full ABS system that quickly inflates two large airbags to help you to stay on top of a slide. When the snow comes to a stop, you're either able to extricate yourself or you're very easy for rescuers to spot and retrieve.
