Kids Trek Pivot Tumbler

The double-wall insulation actually keeps my son's milk cold until lunch, and the handle makes it easy for him to carry. The leakproof straw lid hasn't spilled once in his backpack, which is a huge relief.

I put it in my daughter's lunchbag full of ice water, and six hours later there was still ice clinking around. Even after she dropped it twice, the outside barely has a scratch.

The handle and leakproof straw lid make it so easy for my kid to toss in the car, and it fits our cup holders perfectly. Just wish the double-wall insulation kept drinks icy for even longer on a hot afternoon, but it's still plenty cold after a few hours.
