We’ve tried that lid on the larger version, and it’s great: secure, easy to remove and clean, and fitted with a flexible silicone mouthpiece to prevent soft-palate jabbing. Hydro Flask offers a lid with an integrated straw for its tumblers. The lid still has the usual anti-glug hole, which means it’s not entirely spillproof-we’d never toss the tumbler in a tote bag or backpack-but the slider can reduce, for instance, bumpy-road spillages. The biggest change is the plastic lid it comes with: not the original insulated lid, with one larger sipping hole and a smaller, anti-glug hole opposite, but an insulated lid with a slider that you can open and close. (We measured about 3 inches from the base as the spot where we found ourselves naturally grasping the tumblers.) The construction remains the same (double-walled stainless steel), and the tumbler still comes in eight powder-coat colors as well as three other sizes: 12 ounces, 16 ounces, and 28 ounces. It’s not uncomfortably so, but it’s still perceptibly larger in circumference than the old version.

The current (mid-2022) equivalent of the Hydro Flask tumbler we tested-it now holds 20 ounces, not 22-is about an inch shorter than the original and slightly bigger in girth. (We prefer those to plain stainless steel tumblers because those get uncomfortably hot to the touch if left in the sun.) At the time, the Hydro Flask had the slimmest, most covetable shape of all the tumblers we looked at and came in eight pleasing powder coats. We chatted up a dozen (or more) people over dinner around a campfire, and they all agreed that the Hydro Flask was easier to hold and more visually pleasing than any of the other 16 models we looked at-and that really mattered to tumbler devotees. But the aesthetics were why people loved this tumbler. The Hydro Flask took second place in our heat-retention test, bested by a single degree in temperature, so it will easily keep your coffee hot for the duration of your commute.

The Hydro Flask tumbler now comes with a slider lid.
