Review on FREEMOVE Detachable Phone Pocket Hiking Daypack Backpack - 10L Capacity, Multiple Compartments, Durable - Perfect Hydration Backpack for Hiking, Running, MTB Cycling - Bladder NOT Included by Daniel Truett

Great lightweight hydration pack. Comfortable, padded hip clip and slim design. Some handy tips - trekking pole holder, use FOUR pieces = (elastic loop on top plus black band on bottom of backpack to keep it from dangling) twice. - Pipe Clip: Spin it! to adjust to your angle. - And small flaws (easy to fix): 1. The detachable outer pocket prevents you from swinging your arms when hiking, so it can be easily removed. And 2. The "hard grip" on the neck is annoying so I just cut it off. Overall a great bag. It fits in my 2 liter tank and I can also fit my almost 3 liter tank.
