Summit 兒童吸管蓋水瓶

The double-walled insulation actually keeps the water icy cold through a full school day, even after sitting in a hot car for an hour. The straw lid clicks into place firmly, and I haven’t had a single leak in the backpack since we got it.

The straw lid snaps shut with a satisfying click and hasn't leaked once in my backpack, even after being tossed around all day. My water stayed cold from morning recess until after lunch, which is exactly what I needed.

My son's water stayed ice-cold after four hours at the playground, and the straw lid didn't leak a single drop when he tossed it in his backpack. This thing is built tough enough for his daily adventures.
