The Precision Fuel & Hydration Flow Flasks & Bottle range is designed to make endurance fuelling cleaner, simpler and easier to manage during training and racing. Built specifically for use with Precision Fuel & Hydration Flow Gel, the Flow Bottle and Flow Flasks help athletes track carbohydrate intake more accurately, making it easier to hit fuelling targets without carrying multiple individual gel sachets.

Available in Flow Flask 120, Flow Flask 300 and Flow Bottle 300, the range gives athletes flexible options depending on session length, event type and carrying preference. The Flow Flask 120 holds 120g of carbohydrate and is designed for shorter events and training sessions, while the Flow Flask 300 and Flow Bottle 300 can each hold a full pouch of Flow Gel, giving you 300g of carbohydrate in one bottle or flask.

Designed for runners, cyclists, triathletes and ultra-endurance athletes, the PF&H Flow system helps reduce mess, waste and mid-session faff. Instead of opening repeated gel packets during hard efforts, you can pour Flow Gel into a purpose-built bottle or flask, then use the markings to monitor intake as you go. Whether you are preparing for a marathon, long ride, triathlon or race-day fuelling plan, the Precision Fuel & Hydration Flow Flasks & Bottle range helps you fuel with more control and less disruption.
