Does it keep drinks cold all day?

Double-wall vacuum insulation slows heat transfer, so cold drinks stay cold for hours and hot drinks stay warm through a commute or a work shift. Performance depends on pre-chilling or pre-warming and on how often the lid is opened.

Is it dishwasher safe?

The bottle is stainless steel with a powder-coated finish, and the lid is polypropylene. Hand washing protects the coating and the vacuum seal; the lid can be rinsed and air-dried.

Will it fit in a car cup holder?

It is 3 inches in diameter, which fits most standard car cup holders. The 11-inch height means it may sit tall in shallow holders.

Can I put coffee in it?

Yes. The 304 stainless steel interior is suited to hot beverages and does not hold flavors the way plastic does. Rinse it soon after use to keep the interior clean.

The bottle and its screw-on lid with handle. No straw, brush or extra caps are included.

How does it compare with a Yeti or Hydro Flask bottle?

It offers the same double-wall vacuum construction and stainless interior, plus a handled lid those brands usually sell separately. It gives up their wider lid and accessory ecosystems and their range of sizes.
