Is there a good hydration bladder for backpacking?
I just got back from a backpacking trip and used my CelBak bladder in the pouch included in my backpack. I liked using this system instead of reaching back for a water bottle, but the bladder is hard to refill when buried in the pack and also takes up pack space. Is there another kind of bladder out there? Maybe a square one that can sit on top my gear, near the top of the pack? This would keep it out of the way and make it easy to access. Joseph Moraga, CA
