This Compressport favorite is already well known to all UltrRun S Pack users, but it is now available in one product: the Ergoflask 500ml was designed for ambitious trail runners and fits into a bag or belt Freebelt for easy hydration on the go. The fast-flow valve makes drinking a breeze so you can focus on where you're putting your feet, while the cap is guaranteed leak-proof so you have no surprises. Thanks to its intuitive screw cap, the bottle can be filled easily and quickly at assistance stations, saving you from wasting precious seconds. Its flexible material shrinks as you drink, allowing it to take up minimal volume when empty. 100% PVC and BPA free, the ErgoFlask is also eco-friendly and durable, allowing you to use, wash and reuse it safely. Simply place it in the dishwasher for easy cleaning after your run. Ideal for long distances thanks to its 500 ml capacity, this model completes our Ergoflask range. You can switch from a larger bottle to a smaller bottle depending on the distance of the race or aid stations, in order to stay light and efficient on the course.
