Summit キッズ水筒 ストロー付き

My son can be pretty rough with things, but the leak-proof straw lid has held up perfectly so far. The vacuum insulation actually keeps his water ice-cold even after hours in his backpack.

My daughter’s lunch stayed icy cold until noon, and the leak-proof straw lid didn’t spill a drop when it tipped over in her backpack.

Our kindergartner took this to school in 90-degree heat and after six hours the water still had ice cubes in it. The straw lid is genuinely leak-proof—I tossed it in her backpack sideways and not a drop escaped. This is the first bottle I haven't had to wipe down at pickup.
