Product Description
The Gel Mix Flask 350 ml is the soft flask Maurten built specifically to prep, carry, and drink Gel Mix 480 — nothing generic about it.
Built to Match the Sachet – The fill line and opening are sized around a single Gel Mix 480 sachet, so you're not eyeballing water levels or fighting a narrow neck to pour it in clean.
SpeedFill Cap for Fast Refills – Pop it open, top off at an aid station or your car, snap it shut. The same cap makes rinsing and cleaning between sessions simple.
Bite Valve for Technical Terrain – Get fuel in without breaking stride, even when the trail underfoot demands your full attention.
Gel Mix 480 is pH-sensitive — it stays liquid in the flask, then thickens into a gel once it hits your stomach's acidity, which helps carry the carbs through to your intestine instead of sitting heavy. That reaction only works if the mix ratio is right, which is exactly why a flask built around the sachet size matters more here than with a standard bottle.
How to Use the Gel Mix Flask
Fill it: Add 200 ml of water to the fill line, pour in one Gel Mix 480 sachet, seal, and shake until fully dissolved. Rest it: Let the mix sit for 5 minutes before you start drinking — this gives the hydrogel time to set up properly. Carry it: Slide it into a vest pocket, waist belt, or back pocket for long runs, rides, or race day.
Long-distance runners, cyclists, and ultra athletes leaning on Gel Mix 480 for high-carb fueling use this flask to keep prep simple and consistent, session after session.
This isn't just another soft flask. This is the one built around the fuel you're already carrying it for.
