Collegiate Trek Tumbler

I'm usually skeptical of "leakproof" claims, but this flip lid genuinely hasn't leaked once in my bag, and the double wall insulation keeps my coffee hot through a whole morning of classes. The straws are a nice bonus for when I want to sip something cold instead.

The tapered bottom fits my car’s cupholder perfectly, and the double-wall insulation kept my coffee hot through a two-hour lecture. Tossed it in my bag with the flip lid on and not a single drop leaked—the two straws are a nice backup too.

The flip lid seals tight enough that I tossed it in my tote sideways and zero leaks, which is a huge win for my commute. Double wall insulation kept my coffee hot through a two-hour lecture, and the tapered base still let me wedge it into my bike’s bottle cage.
