HYDRAFLOW Capri - 20oz Tumbler with Straw - Triple Wall Vacuum Insulated Tumbler - Insulated Smoothie Cup - Stainless Steel Tumbler - Reusable Tumbler with Lid - (Powder Aqua)

Product Information

If you get any of the four colored tumblers, the coating feels more tactile than the Hydro Flask’s, like it’s been rubberized.

That may seem overly dramatic, but after seeing other, straighter designs, our testers tended to set the Zoku aside. We measured about 3 inches from the base as the spot where we found ourselves naturally grasping the tumblers. Pelican Travel Tumbler: This was a top performer in insulation, and we really liked the splash guard on this lid.In 2022, we compared the new versions of our top two picks with the old versions to make sure they lived up to their predecessors. However, the Hydro Flask’s performance and aesthetics—even after a redesign in 2022—make it the winner. I come home from work on Friday evening and find that the ice in the cup is still ice on Monday mornings. Finally, although in the past the company had told us that washing its tumblers in the dishwasher or soaking them in hot water might discolor the powder coat, it now says that the tumblers and their coatings are dishwasher safe.

The lid is easier to put on and take off than the Hydro Flask’s, thanks to its much larger thumb tab, and it closes with a pleasing softness. We picked vessels that were similar sizes, but the tumblers still had slight variations that would affect heat and cold retention. Beyond style, Hydraflow champions eco-friendliness by promoting reusable practices and being BPA-free.Our control Slurpee in the standard 7-Eleven plastic cup lasted about an hour, while the insulated counterparts were continuing to hold form at approximately 50% of the original density into hour three.

In temperatures reaching as high as 112 °F, all the tumblers we tested had an effective insulating value, so they can all keep your drink hot or cold for a few hours. We spent an entire evening around a campfire with about 100 industry designers and professionals and asked many, many questions about their tumbler of choice. Every 30 minutes for three hours, we measured the internal temperature with a digital probe thermometer. Now, however, in the place of a regular sipping lid, Klean Kanteen’s tumblers come with a straw-specific lid and a steel and silicone straw—the very same straw, in fact, that is an also-great pick in our guide to reusable straws. It retains both heat and cold only for as long as you need to get from one place to another, and it lets you sip easily while on the move.

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. This slim, powder-coated stainless steel tumbler fits easily in hands and cup holders, and that’s why we love it. Klean Kanteen has since eliminated that 20-ounce size, though, and as of 2022 offers only 16-ounce and 8-ounce tumblers.
