NCAA 2026 Championship Trek Tumbler

The tapered bottom fits my car’s cupholder perfectly, which is rare for a tumbler this size. I’ve already knocked it over twice and the flip lid didn’t leak a drop, so the double-wall insulation is doing its job keeping my coffee hot.

The flip lid seals tight enough that I tossed it in my gym bag without a drop, and the double-wall insulation kept my coffee hot for a good two hours. The tapered shape is a nice touch too, though the straws are a bit flimsy if you’re rough with them.

The double wall insulation does its job keeping drinks cold for a few hours, but the tapered base is a bit too narrow to feel stable in my car's larger cup holder. The flip lid works fine, though I wish the two straws were stored somewhere on the tumbler itself.
