Carry less water and filter on the fly. Building on the innovative PackFlask™ design, this enhanced system features an integrated filter for fast, reliable hydration on the trail. Simply find a water source, fill and drink directly through the high-flow, self-sealing nozzle. The filter screws securely onto the flask, doubling as a squeeze filter for filling bottles or pots at camp. The stretch-mesh pouch securely attaches to your pack harness for hands-free use.
Avoid freezing filter. Freezing may ruin the hollow fiber membrane. If in freezing conditions we recommend you keep the filter in your pocket or near your body to prevent freezing.
