I have two packs that I was about to put up for sale.
1. Dakine Tactic, medium-sized pack. A-frame and diagonal ski carry, loads of pockets for shovel, probe, lunch, camera, etc. Couple years old and in great shape, has seen very little action while actually skiing. $40 shipped
2. North Face Chugach 18. Slightly more compact than the Dakine and made of much stouter nylon. Diagonal and vertical ski carry, vertical snowboard carry. Shovel, probe, and camelback compartments. Nearly new, only used for one heli trip last year. Very nice pack. $65 shipped.
