Depending on the distance between aid stations, pro trail runners alternate between large and small flasks to ensure they never carry excess weight. The reduced volume of our small 300ml hydration running flask make it perfect for sliding into a Freebelt or traveling - or for weight-conscious trail specialists. The wide opening helps to fill the flask quickly at aid stations during a race, saving precious seconds. The flexible material will shrink as the liquid disappears, preventing sloshing and taking up minimum volume when empty. The fast-flow bite valve is intuitive and the cap is leakproof. The convenient ErgoFlask combines practicality with efficiency and ergonomics in a classy blue design to make hydration easy. Eco-friendly and durable, the flask is guaranteed 100% PVC and BPA-free so you can safely use it, wash it and use it again. Simply put it in the dishwasher for easy cleaning when you get back home.
