2L/3L BPA Free Leak Proof Hydration Bladder for Outdoor Activities

Unparalleled Quality

UPBOXN hydration reservoir stands out from ordinary civilian water bladders made of EVA/PEVA materials. Our reservoir is crafted from high-quality TPU material, ensuring no peculiar smell and BPA-free safety. This material is more pressure-resistant, making it ideal for outdoor activities such as climbing, hiking, camping, riding, and running.

Accurate Leakproof Design

The entire 3L bladder features a double soldering sealing side quilting design, providing exceptional durability even under significant squeezing. The self-sealing mouthpiece at one end ensures a secure seal, while the automatic locking connection socket at the other end is equipped with a tightly shaped and adjusted waterproof ring. Once the water tube is inserted, it locks automatically and remains secure, eliminating the risk of loosening.

Seiko Structure Design

Our hydration reservoir boasts an upgraded tightly sealed auto-lock socket that simplifies the insertion process. Unlike other hydration bladders, you no longer need to align the snap. The double sealing design for the wide closure ensures effective protection against leaks and makes cleaning and refilling easy. First, pinch and seal the TPU clip chain, then use the slide-n-seal system to completely lock in the fresh, cool water without any wastage.

Upgrade Every Detail

The 360° rotatable mouthpiece allows for easy adjustment of the water absorption angle while effectively preventing leaks. The internal TPU connection belt ensures a low-profile fit, enhancing comfort during use. Additionally, the 3 connecting handles make it extremely convenient to carry or hang the reservoir outdoors.

High-Quality Use Experience

Our hydration reservoir comes with a 360° long sealed water tube covered in weave nylon, which helps prevent damage from light exposure, keeping the water source clean for an extended period. The 0.4” diameter high-flow water hose enables quick drinking with just a gentle sip. Should you encounter any issues, feel free to contact us for a satisfactory solution.
