I have an older version of this pack from about 3 years ago. I have both avalung and non-avalung versions. This pack has been great. I use both skiing very regularly. The non-avalung has become my school bag. Lugs around pretty much anything and is very comfortable on the back.
This pack is a good daypack as well as short/mid-length day tours. Holds all your avi-gear in the small pack with lots of room for other things in the main pack. Never had any issue.
Ski carry as the diagonal works pretty well. With lots of use the skis wear on the materaial - as expected. But still going strong 3 years later!!!
