I like the ABS Escape freeride, but the one I like the best is the Vario line. The reason I like the vario is because you can have the flexibility to have multiple size packs without the expense of buyin multiple airbag backpacks. With the Vario, you buy a base unit which has the airbags. You then can purchase different zip-on packs depending on what size you need.
The vario currently has a 15L, 30L, and 50L size zip-on backpacks that fit on the base unit. In the future there will also be other sizes that will zip on to the base unit.
We carry the Vario pack in multiple colors and all the Escape line in multiple different colors (rather than just one choice of black w/ yellow).
You can check out the vario and other airbags at:

If you buy your airbag from us, and you deploy it due to an avalanche, we have a form you can fill out, send some pictures, and we will send you a replacement canister for free!
