Why Choose the Maurten Gel Mix Flask?

Carrying multiple single-serve gel packets can be cumbersome and messy on long efforts. The Maurten 350ml Soft Flask provides a cleaner, more efficient alternative by consolidating your liquid carbohydrate intake into one streamlined, compressible flask. As you consume your hydrogel, the soft flask shrinks to minimize sloshing and optimize pocket space.
