컬리지에이트 트렉 텀블러

The tapered bottom fits my car’s cupholder like it was made for it, and the double-wall insulation keeps coffee hot through my whole morning lecture. The flip lid clicked shut tight on the first try, no spills in my backpack. Two straws is a nice bonus, though I mostly use the lid.

I’m a chronic spiller, so the double-wall insulation and that leakproof flip lid are the only reasons my backpack survives my commute. The tapered shape slides right into my car’s cupholder without wobbling, and the two straws mean I always have a spare when I lose one. It’s kept my iced coffee cold

The tapered bottom fits my car’s cupholder perfectly, which is rare for a tumbler this size. The flip lid seals tight enough that I tossed it in my bag without a single leak, and the two straws are a nice backup.
