This beloved Compressport flask is already known to runners around the world, but now it features an improved shape for even greater speed on the trails.
Designed for easy hydration on the go, the new Ergoflask 500ml is tapered at the bottom to help it slide quickly and easily into a pack or a Freebelt.
The quick-flow bite valve makes hydration effortless, so you can focus on where you're placing your feet, while the cap is guaranteed to be leak-proof, ensuring you won't have any unpleasant surprises.
With its intuitive screw cap, this soft flask fills easily and quickly at aid stations, allowing you not to waste valuable seconds.
The flexible material collapses as you drink, ensuring it takes up minimal space when empty.
100% PVC and BPA-free, the ErgoFlask is also environmentally friendly and durable, so you can safely use, wash, and reuse it.
