I'm selling my nearly new Mammut Ride RAS 30L airbag backpack from last year - works great, carries weight really well, but I need to upgrade some other gear. Color is bright green. Airbag can be swapped between any other RAS compatible pack from Mammut, Scott, etc. Bag has been on two tours, mint condition, never been in an avalanche. Combo is easily $750+ new, maybe $680 if you can get in on the right sales.
Price of $500 includes a full cylinder. Can deliver the bag in western WA with a full cylinder. Alternatively, I can ship it with an empty cylinder anywhere.
