Summit Kids 水筒 ストロー蓋付き

The straw lid clicks shut with a firm snap, so I can toss it in the diaper bag without worrying about leaks. Ice from the morning was still clinking around at pickup time, which is exactly what I needed.

My son loves that his water stays cold until lunchtime, and the straw lid is easy enough for him to open on his own. No leaks in his backpack yet, which is a huge win for me.

My daughter’s been using this for school lunches for two weeks now, and the vacuum insulation actually keeps her water ice-cold until pickup time. The straw lid hasn’t leaked once, even tossed sideways in her backpack, and the double-walled steel feels sturdy enough to survive the playground.
