Overview
Munchkin's Cool Cat cup uses double walled stainless steel to hold drinks cool for hours, with a flip top lid over a spill-proof straw. Easy grip handles help toddlers hold it.
Insulation means milk or water stays cold on long outings without ice packs. A sealing ring must be lined up correctly, and a misaligned ring is the usual cause of leaks.
Who it's for
Daycare bags, park trips and car rides suit it. Younger babies under the age guidance should use a lighter training cup.
Pros and cons
- Insulated stainless steel
- Long cold retention

- Heavier than plastic
- Not for babies under the age range
Performance notes
Two steel walls with a gap between them slow heat transfer, which is how drinks stay cold. The flip lid covers the straw, and the seal only holds when its tab matches the gap in the lid.
