A new Era of straw tumbler is here. Our Era tumbler is totally leakproof, and made for stress free sips on the go. It has our fully leakproof Ü-Turn™ lid that works for both cold and carbonated beverages, ColdKey™ metal straw for minimizing the amount of plastic sitting in your water, SoftSip™ silicone straw so every sip feels like a luxury, BevGuard™ technology to keep drinks cold for 24+ hours, and a cup-holder friendly base so you can enjoy 40oz of your favorite beverage, free of leaks and spills throughout your daily journey.


Era Tumblers are 100% leakproof with cold beverages and iced carbonated beverages when in the locked position. A 50% ice to liquid ratio is recommended when using carbonated beverages.


Not recommended to be used in the locked position with hot beverages. Using hot beverages with a straw poses a scalding risk.

Era FAQ

Compatible with cold beverages and iced carbonated beverages.

When using with carbonated beverages on an airplane or at high altitudes, pressure will build up inside and may escape through the straw when unlocking it. To alleviate pressure and prevent this from happening, slowly unlock your Ü-Turn™ lid to release pressure.

To open the Ü-Turn™ Lid for sipping, align the mode indicator with the 'open' position indicated by the raised notch. To lock, turn and line up the mode indicator on the lid with the 'closed' position on the opposite side.

The Era can keep your beverages cold for 24+ hours. It is recommended to use at least 50% ice for maximum ice retention.

Era lids and silicone straw pieces are only interchangeable between 30oz + 40oz Era sizes, however, be sure to use the correct size stainless steel straw attachment as the 40oz straw is longer than the 30oz.

All parts, including the lid, are top-rack dishwasher safe with two exceptions - Dark Aura and Onyx Leopard colorways (these bottles are hand-wash only, but lids and straws are still top-rack dishwasher safe). Remember to remove the straw lid before washing. To do this, simply turn the mode indicator halfway between the locked and open positions and pull up on the straw center piece for easy cleaning. For hand washing, check out our cleaning essentials kit, or read our full guide on how to clean your tumbler.

To remove the ColdKey™ metal straw for cleaning, twist the straw until the notch aligns with the vertical groove and pull down to release the straw.

Era 30oz lids are interchangeable between 30oz + 40oz sizes, however, be sure to use the correct size stainless steel straw as the 40oz is longer than the 30oz. Not compatible with Era 20oz.

Yes. Era 30oz is compatible with our Magnetic Straw Covers to keep your straw protected while on the go, and Era 30oz Lids [hyperlink once we have] so you can mix and match different colors and combinations.
