Braden Masselinkwrote a review of ABS Avalanche Rescue Devices Vario 15 Backpack - Discontinued Model on November 29, 2011
Started with the Vario 30 and like it for extended trips, but found it a little bulky for quick side trips. Purchased the Vario 15 and in seconds had it on to my existing frame and it was out the door. Great pack and the weight you do not even notice after a few laps. No problem with carrying my med kit, shovel, probe, water, and a puffy.
