This Compressport favourite is already well-known by ambitious runners across the globe, but now features an improved shape for even more speed out on the trails. Designed for easy hydration on the go, the new Ergoflask 500ml is tapered on the lower section to help it slide quickly and easily into a pack or a Freebelt. The fast-flow bite valve makes drinking a breeze so you can focus on where you’re putting your feet, while the cap is guaranteed leakproof so you have no nasty surprises. With its intuitive screw lid, this soft running flask is easily and quickly filled at aid stations so you don’t waste precious seconds. Its flexible material shrinks as you drink, ensuring it takes up minimal volume when empty. 1% PVC and BPA-free, the ErgoFlask is also eco-friendly and durable so you can safely use, wash and use again. Ideal for longer distances thanks to its 500ml capacity, this model completes our Ergoflask range ; simply switch between larger and smaller flasks depending on race distance or aid stations, and ensure you stay light, fast and hydrated on the trail.
