Curated, not stocked.
We stock the Gelflask because good nutrition kit matters as much as the nutrition itself. Maurten's hydrogel format is one of the more studied approaches to carbohydrate delivery in endurance sport, and the Gelflask is the practical companion that makes it easier to execute a fuelling plan consistently. For athletes we work with who use Maurten gels regularly, this is a sensible, low-waste addition to their race kit.
About this product
Gelflask
The Maurten Gelflask is a reusable flask designed to carry Maurten's hydrogel-based energy gels during training and racing. Rather than tearing open individual sachets mid-effort, athletes can pre-fill the flask and consume their fuel in controlled amounts without breaking stride. This suits runners, cyclists, and triathletes who prefer to consolidate their nutrition carry — particularly useful in longer events where multiple gel sachets would otherwise mean more pocket bulk and more waste.
The flask is purpose-built for Maurten gels, whose hydrogel matrix has a thicker, more viscous consistency than most conventional gels. The nozzle and capacity are designed with that texture in mind, making it easier to dispense the gel smoothly under race conditions. It is reusable, which reduces single-use packaging across a heavy training block.
This is an accessory rather than a supplement in itself — it contains no active ingredients and delivers no nutritional value independently. Its clinical relevance sits squarely in execution: even a well-designed fuelling strategy fails if the practical delivery is awkward. For athletes following a carbohydrate periodisation protocol or race-day nutrition plan, having reliable, familiar equipment removes one variable from the equation. Pair it with the appropriate Maurten gel for your target carbohydrate intake per hour, as guided by your nutrition plan or coach.

How to use
Fill the flask with your chosen Maurten energy gel before your session or race. Consume as you would a standard gel sachet — sip directly from the nozzle during exercise, following your planned carbohydrate intake schedule. Rinse thoroughly after each use.

Common questions
Frequently asked
What gels is this flask compatible with?
It is designed specifically for Maurten's energy gels, which have a thicker hydrogel consistency. It may work with other gels, but the nozzle and sizing are optimised for Maurten's formulations.
How much gel does the flask hold?
Check the product packaging for the exact capacity. As a rule, it is intended to hold enough gel for one or more standard servings — refer to the label or Maurten's guidance for precise fill volume.
Is it easy to clean between uses?
Rinse with warm water immediately after use. Maurten gels are water-soluble, so residue is generally straightforward to clear, but allow it to dry fully before refilling to avoid diluting the gel.
Why use a flask rather than individual sachets?
For athletes carrying multiple gels over a long effort, a single flask reduces bulk, eliminates the need to open sachets on the move, and cuts down on packaging waste across a training block.
Does this product contain any nutritional value on its own?
No. The Gelflask is an accessory with no active ingredients. All nutritional value comes from the gel you fill it with.
