This pack is great for those days when you aren't hiking a long way from the lifts, and really just need oyur avy gear, some lunch and an extra layer.
It fits snug on your back so you hardly notice it's there, and there's no problem having it on on the chair-lifts.
It fits my G3 avitech shovel perfectly, and allmost seem to be tailored to fit it. I can also fit in lunch, a 3L camelback, some extra layers and gloves, extra goggles, my skins and not much more. I love the hip pockets for phone, camera and other small items wich are useful to have within reach.
Don't buy it if you need to fit your helmet in it, I don't understand why backcountry.com states that you fit the helmet in the top pocket, because you can't. I have also asked about this on the live chat, but they have not corrected this error. Osprey does not say that it fits a helmet in the top pocket in contrast to what they say about the 26 and 36L versions.
