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

Fits great on my Nathan Exodraw and Exoshot soft flasks. These are a good quality and will make a nice replacement when the current valves are worn out.

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.

It’s fit , quality OEM , durability and functionality

These are a good replacement for Gregory 3D water bladder. It’ll fit just like the original mouthpiece. Only thing to note is if you have the Gregory cap it may not be a snug fit. For the price it’s excellent replacement.

Replaced leaking and crusty bite valves.

Replacement for my hot laps bag

I bought this to replace the bite valve on my Osprey Katari 3 bladder. It's genuinely better than Osprey's bite valve design because the plastic insert in the center is rounded rather than a straight 90 degree drop. As a result of Osprey's design choice, the silicon rubber will shear with casual use. I don't see myself having that same problem with the rounded HydraPak design. The silicon rubber also feels more durable compared to my Osprey bite valve, but it might just be because the Osprey bite valve is a couple of years old now. Nonetheless, this is a great buy if you need a replacement bite valve.

Lost the valve on a 2L Hydrapak for Dakine bike pack and I am so excited to find these on Amazon. I did look at Hydrapak website and they carry these but would have to pay shipping under $45 order and I didn't want to buy anything else. Although these are slightly different than the original on the pack, it's a perfect fit! I also think this is a fair price for 2 pack and will now have a back up. I use this item 4-5 times a week so very happy to get the replacement in a day.
