Here's what other sites are saying:
As snowmobiles become better, more and more people are riding into serious avalanche terrain, and accidents are correspondingly on the rise. A heavy sled is more likely to stress deeply-buried weak layers in the snowpack, setting off large avalanches that can have serious consequences, making training, experience, and proper decision-making the most important tools a rider can bring into the backcountry. It also doesn't hurt to have an insurance policy like the Highmark Prime RAS Avalanche Airbag Pack, which is designed to keep you on the surface of a slide if you do get caught.

It also has an external pocket for your shovel blade, a shovel handle carrying system, and an internal probe sleeve for easy access to all your avy tools, should you need them. There's an even a fleece-lined goggle pocket to keep your eyewear safe, and a height-adjustable hip belt that keeps the Prime securel...
