Does the YETI Rambler Jr. keep water cold all day?

Yes. Double-wall vacuum insulation keeps cold drinks cold for hours, which is the main reason buyers choose it over a plastic bottle.

Is the straw cap leakproof?

YETI describes the Straw Cap as ultra leak-resistant, not fully leakproof. It handles normal bumps in a backpack but can drip if tipped upside down.

Yes. YETI states both the bottle and the Straw Cap are dishwasher safe.

It uses the same double-wall vacuum insulation and stainless steel build in a 12 oz size sized for kids, with a straw cap instead of the adult lids.

It covers a lunch and recess for most young kids, but active children or hot days may need a refill.
