NBA Trek Tumbler with Flip Lid

The tapered shape fits perfectly in my car's cup holder, and the double-wall insulation keeps my drink cold through an entire basketball game. The flip lid snaps shut securely, so I don't worry about spills when I toss it in my bag between quarters.

I wasn't expecting the lid to feel this secure—no leaks so far, even when it tipped over in my bag. The double-wall insulation kept my drink cold for hours during the game.

The tapered shape fits my car's cupholder perfectly, which is a huge plus for road trips. I wish the lid sealed a bit tighter to feel truly leak-proof, but the double-wall insulation keeps my drink cold for hours.
