A gift for trail runners, endurance racers, and ounce-counting thru-hikers, the Salomon Soft Flask 500ml/17 oz XA is an ultra-lightweight way not only to carry water but to safely treat water wherever you go! A filter built right into the cap filters bacteria and protozoa as you drink!
The threaded cap houses a high-flow valve that provides a strong flow rate so you can hydrate quickly and efficiently. Below the valve and inside the flask, Salomon's XA filter safely and reliably filters out 99.99% of protozoa, Cryptosporidium, and bacteria. This means you can refill wherever you go to ensure that you stay hydrated without concern that you'll get sick. When you know that filterable water sources will be available, this also keeps you from having to haul the weight of excess water when you're trying to move fast.
The flask itself ways next to nothing and packs down small when not in use. Its PVC-free, BPA-free TPU construction is safe and easily cleaned. Welded seams ensure leakproof performance.
