In reply to damowilk:
What’s wrong with the Osprey Kode? I love it so much that I got it in 30 liters, and the newer version, Osprey Kamber in 42 l.
It literally has everything:
1. Separate pocket for avy gear
2. Light color inside(well, mine is red, but not sure about the other colors, but the avy compartment is orange).
3. A-frame (++ more carrying options)
4. Top lid with plenty of pockets, and it can be taken off to save weight, or extended when you have too much stuff with you.
Additionally it has these lovely features that I can’t live without:
5. External helmet attachment for when your backpack is full, both on top and on the back.
6. Back opening with zipper, and clips to hold the backpack together in the unfortunate event of the zipper breaking (hasn’t happened to me). This is a great feature as it gives a good overview of everything in the pack, and you can easily get to everything, even in the very bottom.
7. Two generous pockets on the hip belt
8. Great camelback system
9. Big zippers and clips so you can handle everything with mittens on.
10. It comes in different back lengths, which is perfect for short people, like me!
I could probably write a book about how much I love this backpack.
Only downsides I can think of is that it’s not very light weight (but it’s very durable), and the top lid clips could be a bit closer together (but this has never been a problem for me). Also, the helmet cover clips could be larger so ther would be easier to handle with mittens.
