Mulebar Soft Flask 250 ml – Soft flask for trail running, running and marathons

Practical hydration for all your outings

The Mulebar Soft Flask 250 ml is a soft flask designed to meet the needs of runners, trail runners and endurance athletes. Compact, lightweight and ergonomic, it makes it easy to carry water or an energy drink without weighing down your gear.

With its 250 ml capacity, it is ideal for hydration sections over distances of 5 to 10 km, while remaining easy to carry in a front pocket, running belt or hydration vest.

A lightweight flask that moves with you

Weighing just 35 g when empty, the Mulebar Soft Flask 250 ml limits the weight carried during exercise. Its flexible food-grade silicone construction allows it to gradually compress as you drink, reducing liquid movement and improving running comfort.

Once empty, it easily flattens to free up space in your gear.

A wide opening for quick filling

The flask features a 5 cm diameter opening, making it easy to:

• fill with water;
• add energy powders;
• clean after use;
• refill quickly at aid stations.

The 50 ml graduations also allow you to prepare your sports drinks precisely.

A reliable leak-proof valve

The Mulebar Soft Flask 250 ml is equipped with a leak-proof valve that ensures controlled flow without accidental leakage.

Its drinking nozzle lets you drink quickly with one hand, without interrupting your stride or risking getting your gear wet.

A dust cap also protects the valve between uses to maintain good hygiene.

Made from food-grade silicone, this flask is compatible with:

• water;
• isotonic drinks;
• energy drinks;
• electrolyte mixes.

Its BPA- and phthalate-free design makes it suitable for drinks intended for sports activities.
