HydraPak Gel Flask (150mL)

The last gel wrapper you'll ever throw away. Fill it with Hydrogel, shake, and carry a whole race's worth of fuel in one soft flask.

What it is

A 150mL (5oz) HydraPak soft flask. About 20 grams empty. Collapsible, so it shrinks as you drink and stops sloshing. Dishwasher safe. Holds 25 to 100g of mixed gel.

Pick your cap

Pop-cap for running: bite, squeeze, done, no hands needed. Twist-cap for cycling: locks closed so it survives a jersey pocket and a rough descent.

How to use it

Add Hydrogel powder, water to the line, cap, shake, let it set for a minute. Sip through the race, rinse at home, repeat forever.

Why Blank's

Better than the old one

Love the flask for running. And easy to clean in the dishwasher!

Loved the flask. I thought it was going to be good big but it fit in my shorts pocket perfectly. It made the gel really easy to get down and it was really nice to not have sticky fingers like with every other gel

I love my gel flask it is very convenient to use and is saving me lots of money by using hydrogel instead of alternative sources. I really like the taste of the berry hydrogel mix!

Exactly what's needed for their gels. There is also a one way valve on these to keep air from going back in the flask.

Amazing gel flask. Got both the twist cap and pop cap and they both work great with the gel. I had one small incident where the gel got clogged at a 4 viscosity with the pop cap but that was due to not mixing the gel enough and still had some clumping

Works well, doesn’t pop open by accident

Excellent

It just works. Stellar for mixing the hydrogel mix. I do wish the nozzle had a cap or a different design; the cup-shaped design of it can hold a few drops of gel, leading to slight leakage when I shove the flask back into a pocket on a run, but it’s minor. Overall, it fits the bill and does the job.
