I've got the avalung version of this pack, 32L size. Just enough room for everything you need for day tours. I carry avy gear, a helmet, camera, goggles, spare mittens, water, and a softshell in mine. If it's cold, I'll stick a down vest in there too.
The avalung gives added piece of mind, though I hope to never need it. I like the separate pocket for shovel and probe. Nice to keep that stuff separated from things you get all the time. I carry my helmet with me and don't like it dangling off the back, so having room inside is a plus.
Carries skis well, though you can tell it's a light pack not designed for large loads when they're on there. The rest of the time, fit is comfortable. When I first got it, I wanted more small pockets to keep things organized, but after using it, I haven't missed them.
Overall, great pack. And when you can get it on tramdock, it's that much better.
