Understand the size you're buying if you want to understand the size of the bag. On the smaller side, this bag is great for touring and still can store other gear outside of the PBS kit. Fits well, and everything functions. The best tool I never want to use unless I have to.

I bought this pack for snowmobiling. It is small but definitely packs a punch. It is super comfortable to wear. Very light weight. I love that the avalanche float portion is removable as well. It is a great size for single day use.

This is a really cool bag in a lot of ways. To start with fully loaded its weight is comparable to my empty first gen BCA Float 32. The airbag system takes up much less room than they traditionally have, which is obviously nice. That said there still isn't a lot room to work with. The 22 liter measurement includes all the pockets, including the tool and goggle pockets, as well as the space taken up by the airbag system, so in terms of real usable space it's more like 15 liters or maybe a little less. I wasn't able to get everything I wanted in it, all the essentials but nothing else. The hip belt is also very thin and unpadded so I had trouble getting the pack to sit comfortably on my hips. The fact that the pack is so lightweight meant this wasn't a huge deal but still not what I would have liked. Other than that the pack is quite comfortable to both tour and ski in.

I'm not quite sure how I feel about the trigger. The T-Grip shape is definitely nice if you're wearing gloves and is probably easier to grab in an emergency but I worry what it would be like if you were wearing mittens. It seems like it could be dangerously difficult, especially since you'll be looking to grab it in less than a second.

Overall I'd say this pack is good but built for a specific person. If you like to run really fast and light with minimal gear but still want the airbag backup plan this is a really great option. If you bring a more standard load with you I'd be looking for something more in the 30 liter range.

I got this bag because it was recommended by the American Avalanche Institute for the Avy 1 course, and I'm not disappointed. For the price range especially, relative to other avalanche backpacks, it's a great deal. I like the storage capacity (maybe a few too many pockets for some), which easily holds my shovel, probe, skins, and snacks, as well as the airbag cannister.
I had a couple issues with the top zipper, but I think it was just a fluke.
The only thing I wish it had is a better mechanism for holding poles (I'm a splitboarder) instead of just the single velcro straps on each side. It did fine, but felt flimsy when not absolutely tight.
Overall, though, a great quality bag that I would trust for all my touring needs.
