Your perfect travel companion

Keep life moving with our 21oz (621mL) bottle and Standard Flex Cap. It stashes easily into a small shoulder bag, your pack’s side pocket, or your car cup holder, and holds enough ice cold goodness to keep you going for hours without weighing you down. No wonder it's one of our bestselling water bottles.

All of our products are made with 18/8 pro-grade stainless steel – a metal recognized for its strength and purity. It also protects against flavor transfer, so today’s IPA won’t taste like yesterday’s margarita.

Along with our TempShield™ technology allowing for the lightest weight and slimmest profile insulated bottle, our signature powder coat adds slip-free grip and extra durability – so you can take your Hydro Flask anywhere, on any adventure.

Sip and enjoy!

Is the Wide Mouth Straw Lid leakproof?
The Wide Mouth Hydro Flip Lid and Wide Mouth Straw Lids are NOT advertised as leak proof, and there is potential for dripping if overturned or shaken. If transporting your flask in a situation where it may not remain upright or could be jostled, we recommend using a sealed lid such as the Flex Cap.

Is there a metallic taste to the liquids kept in Hydro Flasks?
No, there will not be a metallic taste.

Why is there a pinhole on the bottom of my flask?
The small hole on the bottom of your flask is a result of the manufacturing process as the powder coating is applied. It's completely expected and normal. This is surface level and will not affect insulation or performance of your flask.

Can you bring Hydro Flasks on airplanes?
Yes, however, some customers have told us going through TSA they have to be empty. When you fill it up, do not fill it up all the way for the plane ride. Leave some room for pressure.

Will refrigerating my Hydro Flask help things stay colder?
You do not need to refrigerate your Hydro Flask.
