Summit キッズ ストローリッド水筒

The straw lid is truly leak-proof — my son tossed it in his backpack without a single drop escaping. Double-walled insulation keeps his water cold even after hours at school.

The straw lid really is leak-proof—tossed it in a backpack with juice all day and not a single drop escaped. My kid loves that it stays icy cold for hours, and the double-walled steel feels solid enough to survive playground drops.
