Camelbak Big Bite Valve Cover (Blue)

The cap is the best thing as while on treks and trails there is lot of dust in the air. As the mouth-piece is exposed to all this, it can be harmful at times. This cover helps to keep the exposed mouth-piece protected. The cover/cap is done good. It has a snap fit for closure. But like most of the users said, it could have been less bulky-er. Opening and closing the cap, while on the move, is sometimes annoying as it needs both hands to snap-shut it. Installing the cap can be bit of a hassle. You have to pull-out the mouth-piece from the tube, put the cover’s lower part and put the mouth piece back again. Need to be very careful while putting it back, as if the mouth-piece is not fixed properly, it might tend to leak. I think, the cover could have been part of the backpack for some extra bucks. Overall, it’s a must have for every water-bladder.

FYI this is for the big bite valve on the hydration pack, and not the Eddy bottles. I discovered the hard way..! The product is pretty standard, so five stars (even though I haven't used it). Instructions included and there are useful YouTube videos to install it.
