Trek Kids Tumbler with Silicone Straw Lid

The tapered shape fits perfectly in my car's cup holder, and the silicone straw lid really does prevent spills—even when my toddler tries to shake it. I've been using it for walks and errands, and it’s held up great without any leaks. The handle makes it easy for little hands to carry.

My kid’s been using this tumbler for a week now, and the silicone straw lid actually keeps juice from spilling in the car. The handle makes it easy for little hands to hold, and it stays put in the cupholder—no complaints here.

The tapered shape fits perfectly in our car's cup holder, which is a huge win for the morning school run. The silicone straw lid hasn't leaked once in three weeks of daily use, though I do wish the handle was a tad bigger for my son's hands.
