NHL Trek Tumbler

Double-wall insulation really works—my drink stayed cold through a whole hockey game. The flip lid seals tight enough that I tossed it in my bag without worrying about leaks.

The tapered base fits perfectly in my car's cup holder, and the flip lid hasn't leaked once since I started using it at the office. Double wall insulation keeps my coffee hot through a full morning of meetings, and the two straws are a nice bonus for switching to water later.

Left it in my truck overnight and the ice was still clinking around the next afternoon, so that double wall insulation is no joke. The flip lid snaps shut tight enough that I tossed it in my gym bag without a leak, and the two straws mean I always have a backup.
