Dakine Heli Pro and Dakine Poacher packs... also used some Burton snowboard packs. The Heli Pro is 6 or 7 years old, I use it for my Ski Patrol pack 3-4 days a week and in the summer I use it as my motorcycle and mountain bike pack. The Dakine Poacher is a bit larger than the Heli, this is my backcountry pack for snowmobiling and snowboarding. The Dakine packs are great. There are straps on the outside that you can strap snowshoes, snowboards or anything else you might want. The Poacher has many zipper compartments inside the pack to separate stuff. These packs are fairly water resistant also. Very durable packs. I have a Burton snowboard pack that I have used for the last 9 years.
