Osprey Hydraulics Bite Valve Cover Uniseks Reservoiraccessoire O/S

I loved the protection it provides for the mouthpiece. I traveled to Turkey and I cannot begin to tell you how many times my mouthpiece would have been in the dirt when my backpack was taken off! I was VERY thankful for this cover.

S'ajuste parfaitement!

Just take the bite valve off and this fits straight on and put the bite valve back with no interference. When you put the cover over the valve, you do need to 'click' it into place - I spent the first day with it flapping around and not staying over the valve so thought it was a waste of money. Seems well made, I paid around £12 which is a bit steep but if I put my pack down I don't want the valve touching anything on the ground, so it does do the job (once you learn to 'click' it on lol)

上手く装着することが出来なくて、大変だったけど、試行錯誤して、パッキンが外れること無く、ハイドレーション使えるようになり、暑い季節の山行行くことが出来て、着けて良かったです。

The cover will not stay on the bite valve. It is has a very loose fit and just falls off. Actually, you are better off if it does fall off. It creates so much space around the bite valve that more dirt and dust collects around the valve like a bucket. I have read that there was an older cover design for the Osprey bite valve that does actually work so I will see if I can find one. Maybe the positive reviews are for that version?
