Great pack, hydration sleeve could use a little more slack
As with the other reviewers, I absolutely love this pack. It's definitely on the pricey side and I found myself ratcheting up to finally pull the trigger on this bag. I like everything about this bag except for the hydration sleeve, which is pretty tight if you're trying to fit a full 3L hydration bladder (Platypus).
I have to remove a lot of stuff from my bag before I can pull the full 3L hydration bladder down far enough to avoid tubing kinks when the bag is all packed up -- I say pull because I literally have to pull the end of the bladder down into the sleeve. The sleeve is that tight. Would probably work a lot better with a 2L bladder, but why would you get a 2L bladder with a 50L + 10L bag?
UPDATE August 3, 2011: Still a great pack, comfy for skiing (thank goodness for Timberline!). However, the hose clip on the right shoulder strap broke when I carried skis over my right shoulder. Arc'teryx sent me another clip via Express Mail after I told them I need it by August, 12. Great warranty service.
