Portable Water Reservoir for Outdoor Adventures

Unparalleled Quality

Unlike the common EVA or PEVA materials used by ordinary civilian water bladders, the UPBOXN hydration reservoir is made of high-quality TPU material. This material has no peculiar smell and is BPA-free, making it safer and more reliable. Additionally, it is far more pressure resistant, ensuring durability during outdoor activities.

Accurate Leakproof Design

The 3L bladder of the UPBOXN hydration reservoir employs a double-soldering sealing side quilting design on its entire edge. This design is capable of withstanding significant squeezing. Both ends of the water tube feature a self-sealing mouthpiece at one end and an automatic-locking connection socket at the other. The waterproof ring in the socket is perfectly shaped and adjusted, ensuring that the water tube locks fast and remains secure, preventing any leaks.

Seiko Structure Design

The hydration reservoir utilizes an upgraded tightly sealed auto-lock socket, eliminating the need to align the snap when inserting. The double sealing design for the wide closure effectively protects against leakage while making it easy for cleaning and refilling. To seal the reservoir, first pinch the TPU clip chain, then add the slide-n-seal system to completely lock the fresh, cool water without any waste.

360° Rotatable Mouthpiece

The mouthpiece is 360° rotatable, allowing you to adjust the water absorption angle easily while effectively preventing leaks. The internal TPU connection belt shapes a low profile, ensuring comfort when used with a hydration pack. This design enhances user experience by ensuring a balanced and secure fit.

Upgrade Every Detail

The UPBOXN hydration reservoir features three connecting handles, making it extremely convenient for both backpacking and hanging in outdoor environments. The 360° rotatable mouthpiece can be adjusted for comfort and prevents spillage. The internal TPU connection belt ensures a smooth, non-digging profile, providing a comfortable and secure fit.

High-Quality Use Experience

The sealed water tube is 41.5" long and includes a weave nylon cover, protecting it from damage caused by light and preserving the water source's cleanliness for an extended period. The high-flow water hose with a diameter of 0.4" allows you to drink water quickly with just a gentle sip.
