Our take on the Thermos Funtainer Stainless Steel Straw Bottle

The Thermos Funtainer is a 12 fl oz kids' water bottle with a double-wall stainless steel vacuum body that keeps drinks cold for hours. It has a straw lid with a push-button cover and a bail handle for clipping to a backpack or stroller. It suits younger children who want cold water through a straw at school or on outings. Against plastic kids' bottles it insulates far better and resists odors, but it holds less than many 16 to 18 oz rivals and the straw parts need regular cleaning.

Questions and answers

How long does it keep water cold?
The double-wall vacuum insulation keeps cold drinks cold for hours, typically through a school day. It is not designed for hot drinks.
Is it dishwasher safe?
Thermos lists the bottle and lid parts as top-rack dishwasher safe, though hand washing the straw and gasket keeps them cleaner.
