New unopened Camelbak Crux 2 liter hydration reservoir. Bought for a hiking trip recently and then never used (I bought 2 and still have the other one which is now in use). This second one is still in its original wrapper and has never been opened (see photos). The one I use works very well. It does exactly as it says on the packet. Easy to fill and fit inside a backpack with no leaks. Tube, mouthpiece and tap all work exactly as described. These are £39.99 on the Camelbak website. Get yourself a new one for just over half price. UK buyers only please.
