Hydro Flask Rocks

Our take Most everyone can appreciate a strong double espresso to begin the day—or, a three-finger pour of the good stuff to end it. This 10-ounce, double-wall insulated tumbler kept the rocks in our Johnnie Walker Black for well over an hour on an 80°F trip in a California wilderness. Nice touch: The beveled bottom has a pinky finger cutout that lets the glass rest securely in your hand. The insulated lid reduces spillage if the tumbler tumbles over and keeps drinks warm (or cold) longer. Like all Hydro Flask products, this one is bomber: Six months of testing only scuffed the paint.

Trail cred “The stainless steel construction means no taste hangover when switching from coffee to soup to whiskey,” said one tester after carrying the Rocks as her only mug/bowl/glass on a trip to the Sierra Nevada.
