Hydrapak Bite Valve Replacement Sheath - for Hydration Reservoir Soft Flask - 2 Pack, Clear (A181)

Works perfectly as a replacement on running Nathan hydroflask soft water bottle (mine had dirty over time and wouldn’t come clean). Can be easily taken apart to wash, and goes in the dishwasher. Way cheaper than buying a new bottle!

Perfect for 500 ml hydrapak. Fits great no leaks. Broke the original valve while on a run and needed a replacement. A lot cheaper than buying a new bottle glad these are available.

This is a perfect replacement fit for my 10+ year old model osprey bite valve (the red one in the photo)!! Very happy. And it is of good quality materials, does not add any taste, and feels right.

It’s fit , quality OEM , durability and functionality

I bought this as a replacement for my Gregory backpack bite valve. Although a little difficult to put on, it's much better than the one that's standard on the Gregory backpack as that one let in a lot of debris and dirt that (no matter how much I washed it) I couldn't get out. I haven't had any leakage issues or issues with durability.

These are good except I accidentally purchased one size smaller than what I wanted for my water to bladder. The product itself is good though.

Replaced leaking and crusty bite valves.

My hydrapak started leaking and I noticed the mouthpiece had a small cut. I purchased these mouthpieces and they are an exact replacement. Initially the rubber is a little more firm than the original but softens over time. It was very easy to change out the mouthpiece, slide the old one off and push the new one on. I have not noticed any change in water flavor with these mouthpieces.
