Overview
A double wall vacuum insulated stainless steel body holds cold drinks while the exterior stays sweat proof. A flip top cap covers a removable silicone straw, and an integrated carry handle with a soft touch grip suits small hands.
Kids get a bottle they can sip from one handed, and adults get a drop resistant steel body with a straw that comes out for cleaning. The limit is hot drinks, which this bottle is not made for.
Who it's for
Children heading to school, sports practice or camp who carry water in a side pocket or cup holder. Adults who want more volume or hot drinks should look at a larger bottle rated for heat.
Pros and cons
- Vacuum insulated stainless steel
- Removable silicone straw
- Carry handle with soft grip
- Fits cup holders and side pockets
- Cold drinks only
- Small capacity for a long day
- Hand washing is recommended
Performance notes
Double wall vacuum insulation slows heat transfer, which is why cold drinks stay cold for hours. The sweat proof exterior avoids puddles in a bag, and the flip cap covers the straw between sips. The top rack suits dishwasher cleaning, though the maker recommends washing by hand.
