Trek Tumbler - Signatur

I was skeptical about the straw lid being truly leak-proof, but after tossing it in my bag with coffee inside, not a single drop escaped. The handle makes carrying it around the office super convenient too.

The tapered shape fits perfectly in my car's cup holder, and the handle makes it easy to grab while driving. After a full morning commute, my iced coffee was still cold and the lid didn't leak a drop when I tipped it over in my bag.

Ice stayed solid in this thing from my 7am commute all the way through a 2pm meeting, which I did not expect. The straw lid seals tight enough that I've tossed it in my bag sideways without a single drip.
