Hands-Free Trail Hydration: Big Mouth TPU Water Bag
Keep your momentum going without slowing down. The CycleAddons big mouth tpu water bag is a high-capacity hydration reservoir explicitly engineered for mountain bikers, endurance cyclists, backpackers, and outdoor adventurers. Utilizing advanced food-grade TPU construction and a wide slider-top framework, this leakproof bladder provides clean, taste-free water that integrates seamlessly into any hydration backpack.
Why Outdoor Athletes Depend On This Hydration Bladder:
No more struggling with tight, narrow screw caps. The slider top opens fully to allow fast refilling from streams or faucets, easy ice cube loading, and reaching inside for simple scrubbing and quick drying.

Drink pure water without plastic aftertaste. Crafted from medical-grade thermoplastic polyurethane, this reservoir is non-toxic, odorless, highly pliable, and resistant to heavy compression inside packed bags.

Disconnect the drinking hose in one click without spilling water. The integrated stop-valve seals automatically upon hose detachment, making threading tube paths into backpacks fast and mess-free.

Enjoy effortless water flow on the go. The soft silicone mouthpiece features a protective cap to keep trail dirt away, plus a manual turn lever to lock fluid flow completely during transit.
