HYDRO FLASK 21OZ (621ML) STANDARD MOUTH FLEX STRAW CAP
The water bottle for people who fully intend to drink more water… but would also like it to stay properly cold while they get around to it.
The Hydro Flask 21oz (621mL) Standard Mouth Flex Straw Cap is an insulated stainless steel water bottle built for everyday hydration. With TempShield® double-wall vacuum insulation, a leakproof Flex Straw Cap and a cupholder-friendly shape, it's ready for work, school, road trips, beach days, gym bags and everywhere in between.
FLIP IT + SIP IT
No unscrewing the lid every five minutes.
The Flex Straw Cap makes drinking on the go easy — simply flip it open and sip through the straw.
When closed, the cap is leakproof, making it a much better travelling companion than the bottle that emptied itself through your bag that one time.
COLD FOR UP TO 24 HOURS
Hydro Flask's TempShield® double-wall vacuum insulation keeps drinks cold for up to 24 hours.
Add your water. Add your ice. Head out for the day.
It can also keep suitable drinks hot for up to 12 hours, however the Flex Straw Cap itself is not intended for use with hot liquids.
THE 21OZ / 621ML SIZE
At 621mL, this is a seriously handy everyday size.
Enough capacity to keep your water close without carrying around something that feels like you've brought the kitchen sink with you.
FITS MOST CUPHOLDERS
Road-trip people, this matters.
The bottle is designed to fit most cupholders, making it an easy option for the car, commute and everyday running around.
PURE TASTE
The stainless steel construction is designed for pure taste with no flavour transfer.
Today's water doesn't need to taste vaguely like yesterday's drink. Thank you very much.
BUILT FOR EVERYDAY LIFE
Made from durable stainless steel, the bottle is BPA-free and dishwasher safe.
Because a reusable bottle you'll actually use every day should not require an elaborate cleaning ritual.
PICK YOUR COLOUR
Same Hydro Flask performance, multiple colours to choose from.
Pick the one that suits you — or the one you're least likely to leave behind at work, school or the beach.
