Why We Love It The Naked® Running Flask 500ml is all about simple, reliable hydration that disappears when you are on the move. It sits comfortably in running bands, vests, or packs, shrinks as you drink, and never gets in the way of your rhythm. For long runs, races, or everyday training, it delivers smooth flow without sloshing or bulk. Lightweight and easy to use, it is the kind of flask you trust from the first sip to the last. Talk Nerdy To Me Made by HydraPak, this 500ml soft flask weighs just 30g and is designed with a low profile shape to integrate seamlessly with Naked® running systems. The 28mm cap and high flow bite valve provide fast, controlled hydration during hard efforts. As liquid is consumed, the flask compresses to reduce movement and volume. It is 100 percent BPA and PVC free, built for durability, and easy to maintain with hand washing or top rack dishwasher cleaning using warm water.
