Overview
A 12 ounce stainless steel kids water bottle from Thermos in a construction print, insulated to keep drinks cold up to 12 hours, with a push-button lid and a removable straw.
This is a cold-only bottle. Thermos is explicit that it is not built for hot liquids, which matters if a buyer expects an all-purpose thermos. The push-button lid and integrated carry handle are aimed squarely at kids handling the bottle themselves at school.
- 12 oz vacuum insulated stainless steel
- Keeps drinks cold up to 12 hours
- Push-button lid with carry handle
- Removable straw, dishwasher safe
Who it's for
Suits parents buying a cold-drink bottle for a young child's school day or activities, where a lightweight, kid-operable lid and a fun print matter. Not the choice for anyone wanting to carry hot drinks, since the insulation is rated for cold only.
Strengths and trade-offs
Drawn from this product's published specifications.
- Keeps drinks cold up to 12 hours
- Push-button lid is easy for kids to operate
- Straw is removable for cleaning
- Dishwasher safe, though hand washing is recommended
- Not rated for hot liquids
- 12 oz capacity is small for older kids or all-day use
Performance notes
Vacuum insulation between the steel walls is what holds the 12 hour cold rating, and the pop-up straw is designed to stay covered when not in use for hygiene, while still being removable for cleaning. The 18/8 stainless steel construction is the same grade Thermos uses across its durability focused lines, meant to handle drops without denting through.
