TPU Bladder and TPU Tube: TPU material water bladder is cleaner, more flexible and cold resistant than other materials. The thickness of 0.4 mm makes it more resistant to pressure, abrasion and puncture. TPU tube has excellent elasticity and bending resistance which makes it easier to adjust position without kinking when drinking and keeps the water flowing smoothly.
Quick Release Insulated Tube: Shutoff valve prevents the bladder from leaking after the tube is detached, convenient for filling, cleaning and storage. Tube is covered with an insulating waterproof Neoprene sleeve to prevent water in tube from freezing in winter and from overheating by direct sunlight in summer, keeping water fresh and cool.
360 Rotatable Soft Bite Valve: You do not have to bend over or bend the tube too much, can drink easily in the normal position. On-Off valve controls the opening and closing of water flow, no water drips when valve is closed. Tube head can be dismantled for easy tube cleaning. Soft silicone mouthpiece makes the water flow fast, you can suck water simply by biting. Dust cap protects mouthpiece from dust and dirt.
Large Opening for Easy Filling: The opening with an inner diameter of 3.35 inches makes it easier to clean, dry and add ice cubes. You can fill water directly without taking the bladder out of the backpack. Center baffle on bladder helps limit the sloshing of water, keeps bladder flat for easy loading into the backpack.
Versatility: The upper hook and lower handle around the opening allow the bladder to be fixed in the bag in multiple ways, compatible with most hydration backpacks. Frees your hands while drinking, keeps you hydrated when backpacking, jogging, hunting, motorcycling, camping, skiing and snowboarding.
