Mega Flask (450mL)

Three times the gel, same no-wrapper idea. For the days when a 150mL flask runs dry before you do.

What it is

A 450mL reusable soft flask by Endorphin Belt, three times the volume of our regular gel flask. Fill it with mixed Hydrogel or drink mix and carry a long run's worth of fuel in one place.

The belt bundle

The Endorphin Belt is built around this flask, with room for your phone, keys and a spare bag of mix. Flask alone $20, belt alone $55, both together $70.

How to use it

Same as the small flask: powder, water to the line, shake, go. Rinse after.

Why Blank's

One flask instead of nine gel wrappers. A belt that was designed for the flask, not the other way around.

FAQ

How many gel servings does it hold?
Around six at 50g each, depending on how thick you mix it.

Does it fit a standard race vest pocket?
Most front vest pockets are built for 500mL flasks, so yes. Check yours.

What's in the belt bundle?
The Mega Flask and the Endorphin Belt, $70 together instead of $75 separately.
