HYDRO FLASK 21OZ (621ML) STANDARD MOUTH FLEX CAP
Your daily water bottle — the one that goes from the car cupholder to the work desk, beach bag, gym and back again.
The Hydro Flask 21oz (621mL) Standard Mouth Flex Cap is a reusable insulated stainless steel water bottle built for everyday hydration. TempShield® double-wall vacuum insulation keeps cold drinks cold for up to 24 hours and hot drinks hot for up to 12 hours, while the leakproof Flex Cap makes it easy to grab and go.
COLD FOR 24 HOURS
Cold water should still be cold when you come back to it hours later.
Hydro Flask's TempShield® double-wall vacuum insulation keeps drinks cold for up to 24 hours, making this an easy bottle for long days at work, school, travelling or out in the sun.
HOT FOR UP TO 12 HOURS
The insulation can also keep hot drinks hot for up to 12 hours.
Just remember to keep hot liquids out of reach of children.
THE FLEX CAP
The Standard Mouth Flex Cap is leakproof when closed, so you can carry your Hydro Flask without spending the day wondering whether your water bottle is quietly destroying everything inside your bag.
21OZ / 621ML
The 621mL capacity hits that everyday sweet spot.
Plenty of hydration without carrying around a bottle the size of a small household appliance.
FITS MOST CUPHOLDERS
This matters more than people realise until they buy a bottle that doesn't fit.
The 21oz Standard Mouth is designed to fit most cupholders, making it an easy companion for the car and daily commute.
PURE TASTE
The durable stainless steel construction is designed to deliver pure taste with no flavour transfer.
Water tastes like water. Exactly as it should.
DISHWASHER SAFE
Yes, you can put it in the dishwasher.
Because if something is supposed to come everywhere with you, cleaning it shouldn't become another job.
PICK YOUR FAVOURITE
We stock this Hydro Flask in multiple colours, so the hardest part might actually be choosing one.
Or don't. Having a work Hydro, car Hydro and beach Hydro sounds completely reasonable to us.
