Rated 4 out of 5 by from great item This bite valve cover is great for desert hiking because it not only keeps the dirt and sand out, it keeps cactus thorns out as well. Quite a few times I've taken my pack off to scurry under a fence or natural barrier, and when I put my pack back on I've discovered that I got cactus thorns in my bite valve. The little hairy thorns imbed in the soft rubber of the bite valve and they're almost impossible to get out. Not pleasant! Especially when it's hot and you're ten miles away from the car. After a few times of that, I got the bite valve cover and everything stays clean--you just have to remember to cover the valve before you shrug your pack off. The cover is a bit cumbersome but it's well worth the trouble.

Rated 2 out of 5 by from Difficult installation I struggled to get the bite valve cover on properly. I called Cascade (owner of Platypus brand) and they kindly sent me pictures (attached) and explained the installation over the phone without any wait - good customer service. Key inside info is that it might help to put the bite cover and valve stem in warm water before installation so it is more pliable. Still it is a poor design - the Camelback slip-in bite valve cover is far easier to use while actively hiking and is a much better design, although slightly less hygienic I assume. This is a fundamental flaw in the Platypus hydration pack system. Overall, ergonomically, Camelback is easier to use - while hiking and even filling the bladder. Platypus overall is more hygienic and sealed, and the 2-compartment bladder is a stronger design and the bite valve does not seem to leak occasionally like the Camelback does.

Rated 4 out of 5 by from This item should be sold as part of the Platypus system This item should be sold as part of the Platypus system itself. If you don't have a cover the mouthpiece is always exposed to the environment. Installation instructions should be included.

Rated 3 out of 5 by from Help, I dont understand how to put it on my Platypus 2L. I bought these after the fact, because my valve is always dusty when hiking, but the platypus doesn't come apart to slide this on. does it?i didn't want to break the platypus by pulling the hose of the valve if it wasn't supposed to be disconnected. And its on there very tightly!?

Rated 5 out of 5 by from Works perfectly It works as it's intended to be. The problem I had was that I wish there is better instructions on how to install it. It turned out that I needed to take the tip of the mouth piece off, put it into this, then put both piece back on together.

Rated 5 out of 5 by from Exactly What I Needed! I am guilty of being that person who ALWAYS takes off her pack during breaks in hiking. I know you're thinking, "What's wrong with that?" tWithout fail, I am ALWAYS frowny-faced when my pack is back on my back & my bite valve is covered in dirt. My friends were getting sick of cleaning the dirt off so they told me to get a bite valve cover. I did & I love it! It's made from a sturdy material & best of all, it keeps my bite valve clean!

Rated 2 out of 5 by from Doesn't stay closed Bought this for my 2L Platypus Hoser for the John Muir Trail. Was disappointed that the cover would easily pop off leaving the bite valve exposed and dirty.

Rated 5 out of 5 by from Well worth the few bucks! I have this on my 3L Platypus Big Zip reservoir. For the few bucks this costs, it's well worth it. I'm guilty of throwing my pack down wherever (when it's ready to come off it's coming off!) and this little guy keeps the bite valve from getting coated in dirt, sand, pebbles, whatever. Just get it! Took a little elbow grease to get on but it never has to come off!
