Review on 💧 YISMEET Hydration Backpack: Lightweight Water Rucksack with 2L Water Reservoir by Matt Simpson

The pack itself looked pretty solid. It has straps that help hold the shoulder straps together and another that wraps around the waist. When the bladder is full, there is no room for other items, but my car keys, wallet, phone, and power bank easily fit in with a full bladder. Don't expect much more to fit. The bladder seems a little fragile, although I'm not sure how well the higher end brands are researched. On humid or hot and sunny days, the exposed part of the tube heats up. Be prepared for the first puff to be warm if you haven't had a drink in a while. I played Pokemon GO with it. This worked great for my needs. You can put the handset through either shoulder strap, so I routed a USB cable to the strap that didn't have a handset to charge the phone and leave the external battery in my backpack.
