Our take on the 18 oz Kids Wide Mouth w/ Straw Lid & Boot

The Hydro Flask 18 oz Kids Wide Mouth is an insulated stainless steel bottle built for children ages 3 and up, sold with a straw lid and a perforated silicone boot. TempShield double-wall vacuum insulation keeps drinks cold for up to 24 hours, and the 18/8 stainless steel interior resists flavor transfer. The Color Last powder coat is dishwasher safe and stays grippy, and an integrated name tag helps it come home from school. It sits above basic plastic kids' bottles on insulation and durability, and the wide mouth makes filling and cleaning easier than narrow-mouth rivals.

Questions and answers

How long does it keep drinks cold?
TempShield double-wall vacuum insulation keeps contents cold for up to 24 hours. It is not intended for hot liquids or for use in a microwave, stove or freezer.
Is it dishwasher safe?
Yes. The bottle and the Color Last powder coat are dishwasher safe. Hand washing the straw lid parts helps them last longer.
What comes in the box?
The 18 oz wide-mouth bottle, a straw lid and a perforated bottle boot. The bottle has an integrated name tag.
