NHL Trek Tumbler

The flip lid really is leakproof; I tossed it in my bag with no worries and it didn't spill a drop. The double wall insulation keeps my coffee hot for hours, which is perfect for long games.

The tapered shape fits snugly in my car's cup holder, which was my main worry. The double wall insulation kept my coffee hot for over two hours without any leaks from the flip lid. I’ve already used both straws and the whole thing feels solid.

I was skeptical about the double wall insulation, but after letting my drink sit for a few hours during a game, it was still cold. The tapered shape slides perfectly into my car's cup holder, which is a huge plus.
