Shanna S.wrote a review of Platypus Hoser Hydration Bladder on September 1, 2011
Bought this for a trip to Yosemite NP. Did both the Half Dome hike and Mt Conness. Worked really well for the whole trip. Really glad I bought an extra cap. Made it easy to switch between this and my other two Platypus bottles without having to re-thread the tube through my pack. Only problem I had was that screwing on the hose too tight made it leak. Just had to test it by giving it a good squeeze to check for leaks and tighten or loosen accordingly.
