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

Of all the hydro bladders I've looked for, this one turned out to be the best in terms of performance and also at a very reasonable price. I like the big hole at the top. At first I was worried about leakage, but when I use it I can clearly see there will be no leakage. The large opening makes filling and cleaning easier. I also love how it goes from a skinny 2 liter to a fat 3 liter volume by simply detaching the inner baffle. I didn't feel the need to pour in as much as 3 liters so I usually keep it thin, but it's a good option if you're ever in a situation where water is scarce and you need more for a long hike. . I would recommend this brand to anyone looking for a hydraulic accumulator.
