Thermos Foogo Straw Cup

Thermos Foogo is the only stainless steel option in this group and the clear choice for temperature-sensitive use: cold water stays cold for 8+ hours, which makes it the right cup for daycare bags, park outings, and travel. The push-button straw mechanism is both leak-proof and easy for children 12 months and up to operate independently. The stainless steel interior doesn't retain flavors or odors. At $15 it's the highest price here, but for parents who need a cup to last all day outside the house, the temperature retention is genuinely useful.
