Is the Flex Sip Lid really leak-proof?

Yes. Owners report it seals well in bags when the lid is closed properly. Check that the spout is pushed shut before packing it.

Can I put it in the dishwasher?

The bottle body is hand-wash recommended. The Flex Sip Lid has small parts and is best washed by hand to keep the seals working.

Does it fit in a car cup holder?

The 20 oz wide mouth body fits most standard cup holders. Larger Hydro Flask sizes generally do not.

How long does it keep drinks cold?

Hydro Flask rates it for hours of cold retention, and owners commonly report cold water lasting a full day. Hot drinks stay warm for a few hours.

It works for older kids, but the 20 oz size and weight suit adults better. Younger children may do better with a smaller, lighter bottle.

One 20 oz wide mouth bottle with the Flex Sip Lid attached. No extra straws or brushes are included.

About the Hydro Flask Wide Mouth with Flex Sip Lid 20 oz

The Hydro Flask Wide Mouth 20 oz is an insulated stainless steel bottle with a wide opening and the Flex Sip Lid, a leak-proof cap with a flexible straw-style spout. It keeps drinks cold for hours and hot drinks warm, and the wide mouth fits ice cubes and makes cleaning easier than narrow bottles. The Flex Sip Lid is the draw for commuters and gym-goers who want one-handed sipping, though some owners find the lid fussy to clean and the bottle heavy when full. It sits above basic plastic bottles on insulation and build, but costs more and holds less than many 24 to 32 oz rivals.
