NBA Trek Tumbler with Flip Lid

I’ve been using this tumbler daily for my morning coffee runs and the double-wall insulation really does keep it hot for hours. The flip lid gives me peace of mind since I’ve had leaky cups before, and it fits snug in my car’s cup holder without tipping. Definitely a solid upgrade for my commute.

This tumbler fits perfectly in my car’s cup holder, and the double-wall insulation keeps my drink cold for hours. The flip lid seals tight enough that I’ve tossed it in my bag without any leaks.

I was skeptical about the leak-resistant claim, but I've been tossing this in my gym bag daily with zero spills. The double-wall insulation keeps my water ice-cold for hours, even in a hot car.
