Meltonic Eco-Refillable Flask for Gels and Purees 2026

Say goodbye to tedious disposable packaging, simplify your refueling while riding, and consume the right dose of energy on your bike thanks to eco-refillable flasks.

The Meltonic Eco-Refillable Flask is the essential accessory for cyclists concerned about their performance and the environment. Designed in high-quality flexible food-grade silicone (BPA-free guaranteed), it is ultra-lightweight, compact, and perfectly adapted to the demands of the saddle. It allows you to group your energy gels and purees into a single practical container, thus avoiding the multiplication of individual sticks and waste in nature.

One single accessory, two sizes according to your goals on the bike:

• 37 ml Size (Small Flask): A featherweight of only 29g. Ideal for your standard training rides or short competitions. Its capacity allows you to carry the equivalent of 3 Meltonic energy gels in a single compact volume.
• 60 ml Size (Large Flask): An optimized weight of 37g. Perfect for long cyclotourisme rides, demanding gravel, marathon MTB, or bikepacking journeys. It allows you to carry the equivalent of 5 Meltonic energy gels to hold the distance without clutter.

Benefits and technical advantages

• Eco-friendly & economical: By using this empty flask to refill with our eco-refills of gels or our refills of purees, you drastically reduce the use of disposable plastic while optimizing the cost of your sports nutrition per kilometer.
• BPA-free food-grade silicone: The flexible quality of its texture fully preserves the natural flavor and nutritional qualities of your honey gels or savory purees, without any plastic aftertaste.
• Zero clutter: As you consume your energy, the flask compresses on itself to take up minimal space in the rear pockets of your cycling jersey.

Maintenance and cleaning advice

• After use with gels: Rinse the flask thoroughly with hot water to dissolve residual sugars. Once dry, store it in the freezer until your next ride to stop the growth of bacteria.
• After use with purees: Clean the flask preferably in the dishwasher to effectively eliminate traces of lipids, then also store it in the freezer after drying.

Did you know?
On the bike, handling traditional individual gel sticks represents a double constraint: mechanical first, because opening a packet with your teeth while riding destabilizes bike handling; ecological second, because the opening micro-waste (the plastic strip) very easily escapes from the jersey pocket with the wind. The silicone flask solves this problem. Moreover, its flexibility allows a more regular gastric emptying: rather than ingesting a large volume of sugar at once (which triggers digestive troubles), you can split your intake into micro-bites every 15 to 20 minutes for a perfectly smoothed energy flow.
