fits bigger circular bite valves.
was struggling to find a cap that would fit but glad to have found this one from gregory. fits great on my bite valve which is circular (and not oval like a lot of the other ones out there).

Fits perfectly
Keeps bite clean but make sure you don’t store it wet and covered so it can dry out between trips

Fits perfectly
I ordered this bite valve cover to protect the bite valve on my Gregory water bladder tube, as it was exposed to the elements during White Mountains hikes in NH. Used it a few days ago on a 10-mile hike and it did the job.

Fit my Gregory bladder well
This should have been included with the bladder.

Must-have for the Hydro pack.
Keeps dust and hair off the mouthpiece, which has a habit of attracting them. It’s a bit silly that this doesn’t come with the hydration pack though.
