トレックタンブラー - シグネチャー

Finally a tumbler I can toss in my bag without worrying about leaks. The double wall insulation keeps my coffee hot for hours during morning meetings.

I commute daily and this cup fits perfectly in my car's cupholder, which is rare. The handle makes it easy to grab one-handed while driving, and the straw lid hasn't leaked a single drop in my bag.

Ice water still had cubes in it after a full day in a hot car, which I honestly didn't expect. The tapered base fits my cupholder perfectly, and the straw lid hasn't leaked once tossed in my bag.
