The Flow Bottle 300 is a squeezable, soft plastic bottle that holds the full 300g of carbs from one pouch of Flow Gel. It features a graduated scale marked in 60g increments, allowing you to monitor your fuelling down to the gram. Weighing just 51g and dishwasher-safe up to 40°C, it combines practical performance with eco-minded design to help reduce overall CO₂ emissions through its minimal weight.

Meanwhile, the Flow Flask 300 is built for those who prefer something even lighter and more compact. Weighing only 29g, it features the same precision carb-scale and a soft, collapsible body that shrinks as you drink to reduce sloshing. A fast-flow bite valve provides easy access without being harsh on the teeth, and the BPA/PVC-free materials ensure clean, fresh taste with every sip.

Whether you're chasing PBs or dialling in your training nutrition, the Flow Bottle and Flow Flask offer two smart ways to stay on top of your fuelling strategy.

The Flow Bottle and Flow Flask are engineered to hold the full contents of a 300g Flow Gel pouch, allowing you to easily monitor how much fuel you’re taking in. The marked scale in 60g increments helps you stay on top of your nutritional strategy without needing to count individual gels. The bottle’s squeezable form ensures maximum flow, while the flask’s bite valve and collapsible design offer a quiet, low-bulk alternative ideal for racing or trail running.

Both options are made with athlete comfort and usability in mind, being easy to clean, lightweight to carry, and made with safe, taste-neutral materials that won’t affect the flavour of your nutrition.
