Sweat, determination, and a relentless pursuit of excellence have pushed us to introduce the Ergoflask 150ml: the ultimate ally for athletes looking to optimise their nutrition on the go. Developed alongside our pro athletes, this small but mighty flask is specifically designed to bring function to your performance, easily holding specific nutrition such as energy gels or high-concentration carbs for intense training and racing. Compact and comfortable, it fits perfectly in the palm of your hand without distracting you from your effort. It also features a specially-rounded base so you can easily roll it up and squeeze out every last ounce of nutrition. The fast-flow bite valve is intuitive and the cap is guaranteed leakproof so you don’t have to worry about sticky hands. Just like its bigger cousins, this extra-small flask is made from eco-friendly and durable materials that are 100% PVC and BPA-free so you can safely use, wash and use again. Whether you're racing to the finish line of a marathon or exploring new trails in Chamonix, the Ergoflask 150ml is the ultimate companion to stay fuelled, hydrated and fast. So don't let its small size fool you: this is a high-performance powerhouse that will keep you going strong all day long.
