Great day pack but...
I borrowed my girlfriends old squall a few times and thought that it was a great simple pack except that it had no sleeve for a drinking tube and I was not convinced by some of the fabrics that were used.
When I saw that they had brought out a new version with tougher materials and a drinking tube I bought one. The new fabrics look good and the pack is simpler and more streamlined making it fine for riding lifts and having enough room for a day in the backcountry. Unfortunately BCA decided to remove the divider between the avy gear and main compartment, and the opening to get to the avy gear (top) has become a strange combination of a drawstring and a velcro and a rolltop closure. The drawstring does allow you to create a little more room in the pack (say for a helmet on the up track) but this opening is fiddly and I think that I would prefer a zipper to the velcro. The roll top doesn't seem to add any benefit that I can see. If the current design had a zipper to access the avy gear and a divider between wet and dry then it would be no less than perfect.
It loses 1 star for the fiddly closure and the lack of a divider.
