Say goodbye to cumbersome, sloshing bottles and hello to a seamless hydration experience that keeps you focused on the path ahead.

The standout feature of this flask is its innovative "Big Cap" wide-mouth opening. This game-changing design addresses one of the biggest frustrations for athletes: refilling on the move. The generous opening makes refills at aid stations incredibly fast and effortless, saving you precious seconds during a race. It also makes adding electrolyte powders, energy gels, or ice cubes a clean, no-mess process. After your adventure, this same wide opening ensures that cleaning is thorough and simple, keeping your flask fresh and ready for your next session.

Experience the freedom of slosh-free running. As you drink, the flexible flask compresses and shrinks, eliminating the annoying and distracting sound of water bouncing in your pack. This collapsible design not only provides a quieter, more comfortable run but also means the flask takes up minimal space as it empties. Its compact 250ml capacity is perfect for carrying concentrated energy gels, a quick shot of water, or for supplementing a larger hydration system. It slides seamlessly into the front pockets of any running vest, fits snugly in a waist belt, or can even be carried comfortably in your hand.

Hydration is instant and effortless thanks to the high-flow, soft bite valve. It delivers a generous stream of liquid with a simple press, allowing you to drink quickly without breaking your stride or fumbling with caps. The valve is engineered to be leak-resistant, giving you the confidence to store the flask anywhere in your pack without worrying about unwanted moisture.

Built to withstand the rigors of the trail and the demands of intense training, the OTSO Big Cap 250ml Soft Flask is a durable and reliable partner for any endurance activity. Whether you are a trail runner, marathoner, hiker, or cyclist, this flask provides a minimalist, lightweight, and highly effective solution to your hydration needs. Streamline your gear, improve your efficiency, and stay perfectly hydrated from start to finish
