Review on BBAIYULE Hydration Backpack Bladder Climbing by Mark Gardner

I've never owned a hydration pack so I can't compare it to others. This rating is based on my experience with this backpack.1. Lightweight hydration pack, when the water bag is full, the weight is light and not too heavy. 2. There are two zippered compartments for car keys or other sharp objects, and plenty of room for your phone and wallet. 3. This backpack is very convenient for running and cycling. It always stays in the correct position of my shoulder. 4. The only downside is that the delivery was delayed by one day.
