Like new 2012 Float 36 avalanche airbag (WITH CANNISTER) from BCA for $500 + shipping OBO. Got a bigger avy pack for overnight trips so am looking to get rid of this one. Will ship with empty cannister (that's the only way I can ship it). I used it for one season and everything is in perfect condition.
Here is a brief description of the pack: http://www.backcountry.com/backcountry-access-float-36-winter-backpack-2197cu-in
Current year's pack from BCA is $725 (including cannister).
