We get what Beyoncé and Nicki Minaj meant when they said they're "feeling themselves" because after what feels like a year of searching for the Stanley Adventure Vacuum Quencher Travel Tumbler—the cup that nearly had a 100,000 person waitlist since last year—we finally found it in stock at REI

Of course, we're totally patting ourselves on the back for finding this guy, and if you've never heard of the cup, you'll end up thanking us later. Especially if you're always thirsty or are currently expecting like this one buyer who wrote, "I’ve been using this cup nonstop since I bought it (I’m pregnant and drinking about 120 ounces of water a day), and I just ordered two more for my house with the restock today AND sent one to my sister! Cheerful colors, sturdy, keep things cold so well. And I love the portability of the cup holder fitting factor!"

The sleek, stainless steel and dishwasher-friendly cup can hold up to 40 fluid ounces of any beverage thanks to its double-wall vacuum insulation that keeps drinks cold for up to two days or hot for up to seven hours. This makes it the perfect option for keeping your coffee hot throughout the day—or staying hydrated during a long hike. It also comes with a screw-on three-position lid which can be turned in three different ways: a straw opening (for the reusable straw that comes with it), a traditional wide mouth for drinking straight from the cup and a full-top cover for preventing spills. In other words, what's not to love about it?

If you plan on scooping one up, just be sure to add to cart ASAP because it could go out of stock within the hour.
