After moving house I was temporarily unable to find my favorite Camelbak hydration pack so I usually bought the mouthpieces/bite valves that I bought as well have a Camelback 90 degree valve and needed bite valves for it so on a whim I went with this package which also came with the valve. Well, the diameter of the hose turned out to be too large for the Camelbak valve, but the valve in this pack had a choice of two screw ends, the larger of which fit snugly into the hose. So it turned out that this little set of spare mouthpieces and the included valve itself were all I needed to convert a cheap hydration pack into a Camelback drinking experience.
