Shop BrüMate's new 100% leakproof Era Flip tumbler

• BrüMate has released the Era Flip, a new tumbler featuring a 100% leakproof, flip-down straw.
• The tumbler's triple-insulated design is rated to keep beverages cold for over 24 hours.
• Its new flip-top lid completely covers the straw, offering a more hygienic design.
• The Era Flip is available in 17 colors and two sizes, 30oz and 40oz.

With summer 2026 in our sights, staying hydrated is about to get a lot more important. If you’re looking to upgrade your daily water bottle, BrüMate just dropped the Era Flip—the world’s first 100% leakproof, flip-down straw tumbler.

Unlike the original Era that used a rotating dial, the new Flip design completely hides the straw when you aren't using it—making it the most hygienic (and mess-free) tumbler we've seen yet. From the metal 'ColdKey' straw to the 17 different colorways, there’s a lot to love.

Check out the full details below and pick your favorite from the 17 available colors.

Before you add the BrüMate Era Flip to your cart, here are the answers to the most common questions readers already have about the brand’s newest innovation in hydration.

Is the BrüMate Era Flip tumbler really leakproof?

Yes! The Era Flip is designed to be 100% leakproof with cold and iced carbonated beverages when the lid is in the locked/closed position. However, it is not recommended for hot liquids while locked, as pressure can build up.

How long does the BrüMate Era Flip tumbler keep drinks cold?

Thanks to BevGuard triple-insulation, these tumblers are rated to keep drinks icy for 24+ hours. To get the best performance, BrüMate recommends filling the tumbler with at least 50% ice.

Can I swap lids between the 30-ounce and 40-ounce tumblers?

Yes! The lids on the Era Flip tumblers are interchangeable between the two sizes. However, the ColdKey metal straws are different lengths, so you’ll need to make sure you’re using the correct straw for the depth of your bottle.

Is the BrüMate Era Flip tumbler easy to clean?

The lid on the Era Flip tumbler is designed to be easily deep-cleaned. You can remove the SlideSeal slider, the silicone SoftSip tip and the metal ColdKey straw separately to ensure no residue builds up in the seals.

Why choose BrüMate?

While many competitors focus on rugged outdoor heritage, BrüMate identifies as an innovation company that just happens to make drinkware. They pride themselves on world’s firsts, from the first leakproof mug with a handle to the Era Flip, the first 100% leakproof tumbler with a fully covered straw. If a design doesn't solve a real-world problem—like germs on an exposed straw or a bag soaked by a leaky lid—they don't make it. Plus, they stand behind that quality with a limited lifetime warranty on their drinkware, giving you extra peace of mind that your gear is built to last.
