NBA Trek Tumbler with Flip Lid

I’ve been using this tumbler for a week and the double wall insulation keeps my iced coffee cold for hours, even on my commute. The flip lid is easy to open one-handed while driving, and it hasn't leaked once. The two straws are a nice bonus too.

The tapered shape fits my car's cup holder perfectly, so I can sip during the drive without it tipping over. Flip lid stays snug in my bag too, and the two straws are a nice backup when one gets lost.

The tapered bottom fits perfectly in my car's cup holder, which is a huge win for my morning commute. The flip lid hasn't leaked once since I got it, and the double-wall insulation keeps my coffee hot for hours.
