The Platypus Hoser is one of Platypus' most versatile products. A workhorse of a hydration bladder, the Hoser is not just a lightweight, ready-to-use hydration system that can be loaded into any pack. It's also the perfect base for adding Platypus accessories, so it can adapt to fit your specific needs. Updates include a new self-sealing HyFLO bite valve that delivers a 30% increase in flow rate, making it quicker and easier to hydrate on the go. Put the Hoser up by it's hang loop around camp and you have a water source for cooking and cleaning. With a anti-microbial treatment, the Hoser keeps your water fresh and prevents it from developing an unappealing taste. When it's time to take a sip, the HyFLO bite valve offers the highest flow rate on the market. Use the Platypus Hoser on its own around camp for drinking or cooking, or put it in a pack and stay hydrated on the trail.
