NHL Trek Tumbler

The double-wall insulation actually works—my coffee stayed hot through an entire morning of errands. The flip lid seals tight enough that I tossed it in my bag without a second thought, and the two straws are a nice bonus for when I switch to cold drinks. It’s become my go-to for every game day.

I was pleasantly surprised that the tapered base fits snugly in my car’s cup holder without any wobble. The flip lid seals tight enough to toss in my gym bag, which is a huge plus. Only giving 4 stars because I wish the insulation kept my coffee hot just a bit longer.

The tapered shape really does fit in my car's cup holder, which is nice, and the double wall keeps my coffee warm for a decent while. But the flip lid feels a bit flimsy when you snap it shut, and I'm not sure how leakproof it'll stay after a few months of tossing it in my bag.
