After using this backpack for a year the main compartment zipper pulls have fallen off. I used on my avy class and with a small amount of food, a nalgene bottle, a very small first aid kit, and back up gloves, my soft shell was a little too large for the main compartment. Jury rigged zipper pulls became a big pain.
Bite valve froze over every 15 minutes in 20 degree weather. It was a struggle to break it up again. finally gave up on it.
when loaded with avy gear, the aforemention brik a brak, and a snowboard the fact that the hip belt did not really sit on my hips became a strain on my shoulders.
MP3 pocket is asinine. if you are in the b.c., why would you listen to a mp3 player? great place for a snack though.
The good...That said, If i didnt have such a beastly stature everything probably would have fit fine.
avy gear stowed away neatly on the outide, and was easy to access during burial scenarios(it kinda got in the way when my board was strapped to it, which i chalk up to my bad, as i really should upgrade to a split).
when the water was flowing again it was still room temp, just like when i left home.
worked well on fall hikes.
