Precision Fuel and Hydration Flow Bottles

You know the drill — mid-ride, you're trying to tear open your fifth gel packet with your teeth, sticky fingers everywhere, empty wrappers flapping off your bike. And somehow you've lost count of how many carbs you've actually taken in. Here's what most athletes don't realize: your bottle can carry your entire race fuel supply and track your intake for you — if it's built for the job.

The PF&H Flow Bottles and Flasks are the only vessels purpose-engineered to pair with pourable gel, letting you load up to 300 grams of carbohydrates into a single container and sip your fuel on demand — no tearing, no mess, no counting wrappers.

300g of Carbs. One Container. Zero Math. The Flow Bottle 300 and Flow Flask 300 each hold an entire pouch of PF&H Flow Gel — that's 300 grams of carbohydrates ready to go before your race even starts. For athletes targeting 60-90g of carbs per hour, that's three-plus hours of fuel in one place.

Engineered for Actual Flow PF&H tested every bottle and flask on the market before building these. The result is a vessel that dispenses thick gel effortlessly — no white-knuckle squeezing, no gel stubbornly stuck at the bottom when you need it most.

Three Sizes, Every Race Distance The Flow Flask 120 holds 120g of carbs and slips perfectly into a jersey pocket or running vest for shorter training sessions and sprint-distance events. Step up to either 300ml option for long rides, marathons, or full-distance triathlon.

The science on carbohydrate fueling is clear: hitting 60-90 grams of carbs per hour during sustained effort is the difference between finishing strong and running on empty. The challenge has always been the delivery system — carrying that volume of fuel without the chaos of individual packets. The Flow Bottles pair with Flow Gel's specially engineered thinner consistency to let you sip a controlled, steady stream of fuel without stopping or fumbling. You always know exactly how much you've consumed because you can see it.

Load it up: Pour one full pouch of PF&H Flow Gel into your Flow Bottle 300 or Flow Flask 300 before your race — 300g of carbs, ready to go, in 10 seconds.

Sip on schedule: Pull from the bottle every 15-20 minutes during your effort to stay on top of your hourly carb targets without mental math.

Pro tip: Run the Flow Flask 120 in your vest or jersey pocket for sessions under 90 minutes, and anchor the Flow Bottle 300 in your bike cage for long-course racing — they're built to work as a system.

IRONMAN champions including Emma Pallant-Browne and 16x IRONMAN 70.3 Champion Sam Appleton have called Precision Fuel & Hydration their secret weapon — and the Flow system is how they execute precision fueling on race day without distraction.

Stop counting wrappers and start hitting your numbers. Your carb strategy deserves a delivery system that actually works.
