Trek タンブラー

The handle makes carrying it so easy, and the double wall insulation actually works—no annoying sweat on the outside. I've been using it daily for iced coffee and it keeps it cold for hours.

The tapered shape fits perfectly in my car's cup holder, and the lid hasn't leaked a drop during my morning commute. The double wall insulation keeps my coffee hot for hours without any sweat on the outside.

Took this on a hike and the outside stayed completely dry the whole time, no condensation ring on my car's cupholder either. The tapered bottom actually fits where my old mug never would.
