I've done a couple days of touring with the bag, and overall I love it. The chest pockets are convenient, letting me store easy to access snacks and water. I have tested the ski carry at home, and it works well with my 100mm skis. It does bag things well. A few nitpicks:
1: The hook to secure the lid is a bit finicky when wearing thick gloves. And the lid doesn't tighten down enough. If you are only carrying 15-20 liters of gear, the lid will flop around because you can't cinch it down.
2: The waist and chest strap buckles ice over *very* easily. When skiing on a day with fresh snow on the ground, I spent 10+ minutes clearing snow out of the buckles to get them to clip. The snow gets in, and then when you try to clip the buckles you just pack the snow into little crevices and they no longer work. I've never had this issue with other buckles. After a while I stopped putting my bag on the ground without first re-buckling the buckles so snow couldn't get in. Very annoying when friends and powder turns are waiting after a transition.
3: The avy gear compartment is not exactly quick access. In particular, the shovel blade pocket has a full strip of Velcro at the top closing the blade off, which is hard to open with gloves. And the pocket is much deeper than necessary. So getting to the shovel requires: undoing the lid's hook, then undoing the main cinch, then undoing the Velcro, and then digging to get the blade out from the bottom half of the pack, where it has inevitably ended up. I'm going to sew a line across the shovel pocket so that my shovel blade sticks out of the top and I don't have to deal with the Velcro.
I realize I'm sort of mis using the pack. Ski touring on powder days with avy gear and digging pits is not its primary focus. But I love the chest pockets and overall simplicity. This bag with a dedicated avy pocket and better buckles would be an instant re-buy for me. As is, I'll use it for spring touring days.
