## Description



## Features

- Unparalleled Quality - Different from EVA/PEVA materials used by ordinary civilian water bladder, UPBOXN hydration reservoir is made of high-quality TPU material, which has no peculiar smell & BPA-free, safer and more reliable, but more pressure resistant. Suitable for outdoor climbing, hiking, camping and riding and running.
- Accurate Leakproof - Whole body edge of this 3L bladder adopts a double soldering sealing side quilting design to withstand a large degree of squeezing. One end of the water tube is self-sealing mouthpiece and another is automatic locking connection socket whose waterproof ring has been shaped and adjusted tightly. When the water pipe is inserted, it can be auto-locked fast and will not loose.
- Seiko Structure Design - For upgraded tightly sealed auto-lock socket, you don’t need to align the snap anymore like other hydration bladder does when inserting. The double sealing design for wide closure will effectively protect from leakage also be easy for cleaning and refilling. Firstly pinch and seal the TPU clip chain, then add slide-n-seal system to completely lock the fresh cool water without wasting.
- Upgrade Every Detail - 360°rotatable mouthpiece to adjust easily the water absorption angle but effectively preventing leakage, the internal TPU connection belt shapes low profile for hydration pack to have a very good sense of comfort when used. 3 connecting handles, very convenient for backpack or hanging in the outdoor.
- High-Quality Use Experience - L41.5" long sealed water tube with weave nylon cover, can usefully prevent the damage caused by light, keeping the water source clean for a long time. 0.4” diameter high flow water hose makes you drink water quickly only by gently sip.

## Questions & Answers

**Q: Any ideas on removing the terrible taste? Thanks**
A: I have the same issue! 
I’ve washed the bladder with soap and have filled and emptied it various times, even letting it sit for days to no avail. I don’t know what to do to remove the plastic taste.

**Q: Am I supposed to clasp it shut with my fingers or is there supposed to be something to ensure closure, like what comes with a vacuum or seal bag?**
A: Yes, close it with your fingers.

**Q: Can the mouthpiece be removed from the tubing for cleaning?**
A: You can take off the silicone part of the water bag throat and then clean the hose.
The water hose can also be taken off at the self-locking socket through the water bag, which is more convenient for cleaning.

**Q: I'm placing a tremendous effort to suck the water out and the flow is very low. Any idea why?**
A: You have to "bite" down on the mouth piece to open the flow

## Customer Reviews

### ⭐⭐⭐⭐⭐ never thristy!
*by M***H on July 1, 2025*

easy to clean, no taste of plastic and easy to fill.

### ⭐⭐⭐⭐⭐ Awesome !
*by J***. on October 29, 2024*

Easy to fill. Love the slimmer design. Fits in my tactical backpack much better than the regular 3 L bladders. Used it at least a dozen times now and haven't had an issue. Only con if I had to mention one is the mouthpiece will drip/leak a little water so I have to keep the hose up or it will leak onto the floor. And it will drip out when using it. But not enough that I'm concerned with losing too much water so I put up with it.

### ⭐⭐⭐⭐ Good Bag
*by J***. on September 12, 2024*

The design is great on this bag but has some minor flaws. I love the actual bag part of this the most. It is a good quality construction with a zip lock top. I love the connectors inside the bag to keep it slim and not bubble out in your pack. The bite valve is average and I am not sure if it can be replaced with another bite valve because of the woven nylon hose. I am just particular about my bite valves and often replace them on other bags. This valve does the job and is by far not the worst I've ever used. My least favorite part of this product is the slip on plastic hanging device. It is so hard to put on and remove. I had to remove the center white plastic and slide it and the bag into the gray hanger. I think the pros outweigh the cons for me and would probably buy again.
