Good adventure backpack?

[xzyragon]

Hey guys! I'm looking into getting a backpack for hiking / rock climbing adventures. It's probably mostly going to be used for day trips, but would need to be able to hold my 7D + ~3 lenses, carry a tripod, and have enough space for a couple water bottles and some food. If anyone has had experience with anything, that'd be awesome to hear your input.

I'm willing to spend about $100 - $150 on one.

Thanks in advance!
