Ergoflask 500ml

This Compressport favorite is already well-known among ambitious runners worldwide, but now features an improved shape for even more speed on the trails. Designed for easy on-the-go hydration, the new ErgoFlask 500 ml has a tapered lower section, allowing it to slide quickly and easily into a backpack or Freebelt. The fast-bite valve makes drinking effortless, so you can focus on your footing, while the cap is completely leak-proof to ensure no unpleasant surprises.

Thanks to its intuitive screw cap, this soft running flask is easy and quick to fill at aid stations, so you don't lose valuable seconds. The flexible material shrinks as you drink, ensuring the flask takes up minimal volume when empty. The ErgoFlask is 100% PVC and BPA-free, eco-friendly, and durable, so you can safely use, wash, and reuse it. With its 500 ml capacity, this model is ideal for longer distances and makes the perfect addition to our ErgoFlask collection. Easily switch between larger and smaller flasks depending on the distance or aid stations, and stay light, fast, and well-hydrated on the trail.
