Trek Tumbler Silikone-bund

The silicone is surprisingly thick and grippy, so it doesn't slide around on my desk when I set the mug down. It's already saved the bottom from a few hard knocks in the car, and I love that it muffles the noise completely.

The clatter when I set the tumbler down is basically gone now, and it feels like a solid cushion underneath. It's already taken a few accidental knocks against my desk without leaving a mark.

The silicone grips the tumbler snugly without sliding around, and I love that it absorbs the thud when I set it down on my desk. My tumbler already survived a couple of drops with zero scratches, so it’s doing its job.
