Two drinks. One cup. Zero juggling. If you’re always carrying a coffee in one hand and a water bottle in the other—or you’re a mom whose kid insists on sipping from your cup—Splitflask is the smarter way to stay hydrated. This 30oz dual-chamber insulated tumbler gives you two separate 15oz chambers inside one stainless-steel body, so you can carry hot and cold at the same time without hauling two tumblers. Mom Hack: Two Drinks, No Backwash Kids love drinking from “mom’s cup,” and moms don’t love the backwash, crumbs, and mystery floaters. With Splitflask, you can make one chamber their “kid side” (water, juice, milk) and keep the other side for your coffee, tea, or sparkling water. They feel included—you keep your drink clean. Perfect for Every Daily Combo Coffee + water on the commute Pre-workout + post-workout at the gym Iced coffee + sparkling water at your desk Tea + juice on school runs A fun drink + a chaser (no judgment) If you’re a two-drink person, this tumbler frees up both your hands and your bag. Realistic Hot & Cold Performance Splitflask is engineered for real-life use, not “24-hour” lab claims. What most customers experience: Hot side: stays comfortably hot ~1–2 hours Cold side: stays chilled with ice for several hours Cold + cold: both sides stay cold significantly longer If you finish your drinks within a couple of hours and refill, this fits your routine perfectly. Leak-Resistant Chambers That Stay Separate Each side has its own channel and seal. To keep flavors and temperatures separate: Fill the cold side first, then pour your hot drink into the other side. Don’t overfill—leave a little room at the top. Align the lid’s center strip with the metal divider inside. Press down and give a short quarter turn to lock. When used correctly, customers routinely report no mixing and no leaks, even in bags, car cup holders, and on-the-go situations. Built for Daily Use, Not Just a Cool Idea 18/8 stainless steel, dual-wall insulated Leak-resistant lid with straw (cold side) + sip opening (hot side) Powder-coated finish with a grippy feel Rubberized non-slip base—no loud metal “clang” Dishwasher safe BPA/BPS-free contact surfaces Fits most car cup holders Splitflask is more substantial than a regular tumbler—most customers call it “solid and sturdy,” not flimsy or lightweight.
