Review: Keeps bite valve clean! - So nice to have for activities where the bite valve ends up touching dirt/sand/etc.. Keeps it clean and ready to drink from!
Review: Recommended to keep your bite valve clean when your pack is off - Personally I like having a cover for my bite valve. I don't necessarily keep it on while we're actually moving on a trail. But it is really nice in a pack line or other situation to prevent your bite valve from getting knocked over in the dirt. I think it was a good value and easy to use. It fit my Gregory bite valve excellently and seems durable.

### ⭐⭐⭐⭐⭐ Great! The pack should come with this!
*by R***E on April 25, 2026*

Wonderful! The pack should come with this to keep the valve clean while hiking. 1 problem: water gets caught in there somehow and it drips during hikes and in the car. I don’t really mind but some might.
