Drinking more water is easier said than done—but finding the right water bottle can make it more fun (and feel less like a chore). While there are lots of options out there, the TikTok viral Stanley cup continues to reign supreme for many hydration enthusiasts, including a few SELF editors.

Everyone knows that hydration is key – great for skin, hair and, of course, your health. But no one could have predicted Stanley cups going viral and becoming the IT accessory this year.

As if Black Friday weren’t exciting enough, Stanley’s latest H2.0 FlowState Tumbler drop is here, and the company has obviously nailed the energy of the day.

Owala fans can expect to see a bit of savings on Amazon as holiday sales ramp up. For instance, the popular FreeSip bottle is currently on sale and marked down 17% ahead of Black Friday. The leak-proof bottle comes in a variety of colorways, including a few multicolored options that will help you find the perfect pick anyone on your shopping list.

The best time to buy a new editor-tested water bottle is Black Friday. Grab deals up to 25% off bottles for working out and more from Stanley and Owala.
