Trek 隨行杯

It fits in my car’s cup holder without wobbling, which is rare for a tumbler this size, and the handle makes it easy to grab mid-drive. The lid seals tight enough that I tossed it in my bag with no leaks, and the clear straw is a nice bonus for seeing how much I’ve drunk.

The dual-straw setup is a nice touch—the clear Tritan one feels sturdy and doesn't warp. Lid seals tight enough to toss in my bag without leaks.

The tapered shape fits perfectly in my car's cup holder, which was a pleasant surprise. The handle makes it easy to carry, and the included straws are a nice touch. Only wish the lid seal was a bit tighter to prevent occasional drips.
