Review on 💦 HydraPak Shape-Shift Water Bladder/Reservoir for Hydration Backpacks - 2 or 3 Liter, High Flow Bite Valve: Safe, Reliable & Low-Profile by Tom Bennett

I have two running packs and got them to replace another 1.5 liter reservoir. I have a 2.0 liter and a 1.5 liter hydro pack. The 1.5 liter is slightly better for my pack, the 2.0 liter is for longer runs. Flexibility, easy filling and easy cleaning are excellent with this product. You can turn the balloon inside out except for the clip at the top of the packaging to allow it to dry completely. Apparently it can even be washed in the dishwasher, although I haven't tried it. The mouthpiece is also easy to detach, allowing you to clean and drain the hose with a hose brush. I like the bite valve design with a cap to avoid leakage during shipping. Tip: Buy an extra bite valve in case of an emergency. Mine went halfway through a 23 mile trail run. I got wet from the water running down my front. If I used a hose with a check valve or a spare bite valve everything would be fine.
