غطاء صمام العض

I was skeptical a tiny cover could make a difference, but after a dusty trail run the valve was completely clean while my buddy's was gritty. It also seemed to keep the mouthpiece from icing up on a chilly morning ride, which is a nice bonus for such a simple piece of gear.

The little flap snaps on tight and actually keeps the valve clean even when I drop the hose on the trail. Also noticed it’s helping with the freezing issue on colder morning rides, which is a nice bonus.

Dust and grit used to sneak into my bite valve every time I hit the trail, but this cover snaps on tight and keeps everything clean. It even seems to buy me a little extra time before things freeze up on frosty morning rides.
