Bought this vest new a few years back. I am getting older and find that I don’t use it much. This is very gently used. Don’t know if I have wore it more than 6 or 8 times since it was purchased. I still have the boxes that the components came in. Air canister included. This vest has two big pockets in the front. It has good padding for that extra protection. The vest is a large/extra large with three adjustments small, medium and large. Zippered front. Activation tether can be mounted on the left or right side. The back pack has lots of storage space and an area to carry your avalanche probe. On the back of the pack is an area to carry a shovel. I really liked this feature as the shovel is already put together and you just unsnap and the shovel is ready to go. This is really a plus when time counts. Save yourself a lot of money. When you buy a new vest you have to pay extra for the air canister which is $215.00 . New vest is $880 plus $215 for air canister plus tax. In my state that would be another $100. Total new $1193. Again very little use in this pack. No rips, tears or cuts. Looks new. Save yourself money selling for $750 or best offer.
