Does it really keep water cold all day?

Echo claims up to 24 hours with ice thanks to vacuum insulation. Owners generally report cold water lasting a school day.

Is it leak-proof in a backpack?

The lid locks and flips shut, which limits spills. Some owners report leaks developing over time, so check the lid seal.

It suits younger kids and short outings. Older children or full school days may need a refill or a larger bottle.

It is sold as a cold-drink bottle. Do not use it for hot liquids, especially with a child using a flip lid.

Hand washing the body and lid is safest for the sleeve and locking mechanism. A bottle brush reaches the base.

The slim 12 oz body generally fits kids' backpack pockets and many cup holders, though the sleeve adds a little width.
