25L Insulated Hydration Backpack with 2L TPU Bladder, Hiking Water Pack with Storage for Men Women, Cycling Camping

Built for serious day hikers, multi-day campers, and long-haul travelers, this 25L insulated hydration backpack pairs a 2L food-grade TPU water bladder with roomy multi-compartment storage so you can carry water, snacks, layers, and a tablet without juggling a second bag. Sized 18.90 x 11.02 x 7.48 in. (480 x 280 x 190 mm) and weighing just 1.65 lb. (0.75 kg) empty, the pack puts a 25L cargo volume on your back while still riding light. The waterproof polyester shell brushes off afternoon rain showers and the everyday scrapes of brush and stowed luggage, and brand zippers tested through 3000 cycles keep gliding season after season. Breathable mesh back padding ventilates sweaty climbs, while foam shoulder and waist straps spread the load to ease pressure during long miles. Inside, the 2L TPU bladder uses an automatic shut-on/off valve, sealed detection, and a wide-mouth fill opening that speeds up trailhead refills and makes home cleanup easier after sticky electrolyte drinks. A 360 degree dust-cap mouthpiece, ergonomic handle, and safety whistle round out a kit aimed at travelers who want one pack for everything from a Cascades summit push to a city-to-city train trip.
