Review on TETON Sports Oasis Hydration Backpack - 2-Liter Water Bladder for Backpacking, Hiking, Running, Cycling, and Climbing by Robert Buenconsejo

I bought 2 of these for a trip to San Francisco and Sequoia/Kings Canyon. They were perfect for both of you. I've since bought 3 more (now I have one of each color) so the whole family has one. We love her. You can actually fit a ton of stuff in it, and bungee straps are great for attaching trekking poles etc (I added a couple of D-ring clips). You can also tightly sync the bag if you don't carry much. The hydration pouch is perfect, although we took 2L of extra water with us on longer hikes. I've used many of these bags, mostly from more expensive brands, and they're as good or better than anything I've tried. I highly recommend them. We have no complaints.
