I got the Dakine Pro 2, and so far im really happy with it, its stayed dry (and I had to dig it out of about 4-5" of snow it was snowing so hard when we took a break) has a waterproof camera pouch, front pouch for shovel, proble, and shovel handle (or you can also put it on the outside), as well as some emergency supplies etc., then another pouch behind it that holds a hydration pack, extra gloves, extra sweathshirt, lunch easily, and in case your pack is not full, it has a nice thick ergonomic foam backing that feels nice against your back so the shovel blade dosnt dig in. Straps for holding skis/snowboard upside down, rightside up, accross, and in 69 position, its crazy really, but all fold up nice and neat when not in use.
Straps around your waist, nice and light, comfortable, don't even feel it, and best of all I got it for $34.99 on black friday, I think now you can pick em up for $50-$75 now, you ca check em out on there website, they have all the packs there, and they make some pretty decent gloves too.
