Review on Optimized Insulated Hydration Backpack | Lightweight Day Pack for Hiking, Running, Cycling | Includes 3L BPA-Free Water Bladder by Robert Elder

I took it on a 5 day trip to Disneyland and it worked great. The hip belt pockets fit my large iPhone (in a case) and accessing the phone for photos was easy. The bubble did not leak and chilled the ice water for several hours. The only disappointment, which was minor, was that the snorkel to the mouthpiece didn't cool the water despite the insulation. I was over the moon not suffering from dehydration on a 32 degree day in the happiest place on earth.
