Explorer Thermo Tumbler

My iced coffee stayed cold through a full day of hiking and the drive home—12 hours is no exaggeration. The double-wall design means zero condensation on the outside, which I appreciate when it’s sitting in the cup holder.

The double-wall actually works — my water was still frigid after a full day of beach trips and grocery runs. It’s got a nice heft to it, not flimsy at all, and the lid seals tight enough that I tossed it in my bag without a single leak.

My coffee stayed icy for the whole six-hour drive, and the double-wall really does its job even in the sun. Easy to sip one-handed at the wheel, too, which is a bonus.
