Mix your own EnduroMix and fill your FitterFlask with the 'extra energy' you need for training  or racing.  Each flask holds 250ml (a quarter of a normal bike bottle) and fits perfectly in your rear jersey pocket or in your hand while running, hiking or walking.

Mixing 1 scoop of our own FitFuel Lime/Lemon EnduroMix in the flask will give you 120 calories, 30g of Carbs, 200mg Sodium, and 50mg of Potassium.

Of course, you can add any alternate powder or fluid mix of choice to customize your own 'Power Flask.' For example, mixing the EnduroMix and the TurboShot could give much needed energy and focus over long training/racing sessions!

• Easy to Use and store 250ml Flask
• Detachable top cap
• Self-sealing nozzle which opens with gentle bite-pressure
• Easy to rinse and keep clean
• Made from recycled and BPA-free material
