The Gregory is a fine pack for the price. It held more and cost less than the Camelpack, and at the time, Platypus didn't make anything. It's held up over the past 2 years, but Gregory doesn't make an insulator for the tube, so you're water is always warm until you suck out the water in the tube.

RECOMMENDATION: Buy the pack that has an insulator for the tube. I repeat, buy the pack that has an insulator for the tube.

Customer Service
