Hydro Flask Kids 12 Oz Tumbler with Press-In Straw Lid – Insulated Stainless Steel Cup in Mermaid Green

The mermaid green is her favorite color in the whole world apparently. She carries it everywhere. No leaks when tipped over on the couch, which parents will understand is the real test.

Small enough for little hands, tough enough for daily backpack abuse. Straw is easy to sip and the lid resists leaks well.

The color is even prettier in person. Only thing is 12 oz runs out quick for my four-year-old, so refills happen a lot. Keeps water cold though.

Solid build and it does keep drinks cold. But the straw can pop loose if my son chews on it, and he chews on everything. Fine for a calmer kid.

Perfect.

One per kid plus a spare. They've been dropped on tile, left in a hot car, and run through the dishwasher weekly — still sealing and still cold. The press-in straw lid is genius for the 3-5 crowd.

That was my main requirement and it delivers. Also fits small hands, doesn't sweat, and cleanup is quick. Wish it came in more colors.

I keep one at my house for when the grandkids visit. It doesn't leak on my furniture and the kids can open it themselves. Simple and well made.

One drop on the driveway and the press-in lid popped off, spilling everywhere. Bottle survived but the seal hasn't been the same since.

My daughter picked it out herself and now drinks way more water. Insulation works, straw is easy to clean with a thin brush, no complaints.

Transitioned my three-year-old from sippy cups to this and it went smoothly. She figured out the straw instantly. Minor condensation on the outside in humid weather but nothing dramatic.

Thrown, dropped, rolled off the high chair tray — still no dents and no leaks. This thing is indestructible. Cold milk stays cold too, which matters more than I expected.
