Crafted with high-strength 3D welds and a flexible, durable build, the Drinkflask compresses as you drink, minimising sloshing, enhancing comfort, and maintaining a stable fit against the body. The wide 42mm neck makes filling and mixing easy, while the bite valve ensures smooth, controlled flow on the move. Whether you're navigating climbs or cruising descents, this flask keeps your fuel secure and accessible.

The design fits snugly into most trail running vest chest pockets, helping you stay balanced and efficient without interrupting your rhythm. BPA and PVC-free, freezer-safe, and built for rugged conditions, it meets the demands of endurance athletes who want to fuel smart and move freely.

With the Maurten Drinkflask 550ml, hydrogel fuelling becomes intuitive, less hassle, more performance.

The Maurten Drinkflask 550ml is purpose-built to make hydrogel fuelling seamless. Its extra volume allows for complete dissolution of either Drink Mix 160 or 320, enabling the patented hydrogel technology to form properly. The soft, collapsible structure reduces volume as you drink, limiting movement and maintaining stability, ideal for technical trail conditions where balance and focus matter.

Its bite valve and flexible form let you fuel quickly and comfortably, without needing to stop or fumble with hard bottles. The wide neck simplifies prep and cleaning, while its compatibility with most running vests ensures it stays close at hand for when you need energy most.
