The Water Buffalo Hydration Pack Backpack weighs just seven ounces, and with its ventilated shoulder straps and easy access drinking tube, it’s an impressively comfortable option. In fact, some reviewers even say they forget they’re wearing it while running or hiking.

The pack holds two liters of water, and drinking is easily accessible with a push/pull bite valve on the hose. In addition to the water bladder, the backpack also has a roomy zippered main compartment that can hold up to five liters’ worth of other trail gear. An exterior velcro pocket allows easy access to small essentials, such as keys or your smartphone. Other features, including visible reflector strips and a safety whistle set this hydration pack apart.

Another reviewer emphasized that it’s the perfect size for moderate activity and “smaller day hikes” in particular. “This bag is ultra light and very comfortable. I purchased it to use mostly in my local forest, where elevation gain is sub 400 but [I] still want a water bladder as I usually hike a minimum of 5 miles,” they wrote. “It’s breathable and I usually forget I’m even carrying it. I occasionally trail run and it stays right in place.“Whether you’re an avid hiker in your own community or you’re planning a camping trip where you’ll be hitting the trails, you won’t want to miss out on this lightweight, comfortable, and functional hydration pack.
