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

Every 30 minutes for three hours, we measured the internal temperature with a digital probe thermometer.

Can it meet an entire day’s worth of needs as a singular vessel: sunrise coffee, mid-morning smoothie, ice water with lunch, afternoon lemonade with the same ice, sunset beer, evening cocktail, nighty-night tea? 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. However, the Hydro Flask’s performance and aesthetics—even after a redesign in 2022—make it the winner. 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.The 20-ounce version we originally tested was in the exact same group of finalists in our cold tests as the Hydro Flask, though it didn’t do as well at keeping heat; after 2. The standard lid has a medium-size opening at one side of the mouthpiece designed to restrict flow from hot drinks yet allow cool beverages to pass with fluidity. 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.

Join the Hydraflow team in making a stylish and sustainable solution for your daily hydration needs.The best choice in tops has an all-in-one integrated lid that closes completely and can accommodate a straw. 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. We prefer those to plain stainless steel tumblers because those get uncomfortably hot to the touch if left in the sun. Whether it’s finding great products or discovering helpful advice, we’ll help you get it right (the first time).

The stainless steel tumbler itself is very similar to our top pick, except for a slightly wider taper (it feels more like a pint glass) and a grippier color coating. The lid still nestles down into the cup, leaving the edge of the steel tumbler exposed; we didn’t notice any metallic taste, but if you don’t like drinking from metal tumblers, this might be a dealbreaker.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. That also lets you make your smoothie, go to the gym, and still have a cold, refreshing drink waiting when you’re done. All 15 sat in the front seat of the sedan on the roof of a downtown parking garage, where the internal temperature topped out at 112 °F. This slim, powder-coated stainless steel tumbler fits easily in hands and cup holders, and that’s why we love it. The 16-ounce Klean Kanteen Insulated Tumbler resembles our top pick in many ways, from its insulative performance to its minimalist aesthetics.
