Design & Build Quality
The BrüMate Era 40oz showcases sophisticated design that immediately distinguishes it from budget alternatives. The sleek, single-color construction creates a cohesive, premium aesthetic where the tumbler body, handle, lid, and straw all match seamlessly.
The stainless steel construction feels substantial and durable. The exterior is both attractive and robust, exhibiting a balance between aesthetics and practicality, built to withstand the rigors of daily use Logitech. The powder-coated finish resists fingerprints and provides a comfortable, non-slip grip.
The ergonomic comfort-grip handle is thoughtfully designed and positioned for natural carrying. Unlike some tumblers where handles feel like afterthoughts, the Era’s handle integrates smoothly into the overall design while providing secure, comfortable transport.
The rubber grip makes opening the tumbler easy without touching the straw Abt, a hygienic design detail that’s especially appreciated in shared environments or when hands aren’t perfectly clean.
The tapered base design serves dual purposes: ensuring cupholder compatibility while providing stability when set on surfaces. This intelligent engineering allows a generous 40-ounce capacity without sacrificing portability.
The Revolutionary Ü-Turn Lid — True Leakproof Performance
This is where the BrüMate Era truly distinguishes itself from competitors. The BruMate Era is completely leakproof for both cold and carbonated beverage varieties Amazon, a claim that has been verified by extensive user testing and professional reviews.
How Ü-Turn Technology Works
The patent-pending Ü-Turn lid features a rotating locking mechanism. To open for sipping, align the mode indicator with the raised notch indicating the ‘open’ position. To lock completely, rotate the indicator to the ‘closed’ position on the opposite side. In locked position, the tumbler is genuinely, completely leakproof — you can toss it in your bag, backpack, or car without any concern about spills.
For users looking for a 100% leakproof tumbler, the BruMate Era is the only choice. While the Stanley Quencher and HydroFlask All Around Travel Tumbler are great for several other reasons, the Era is the only tumbler that’s going to be truly spill-proof Amazon.
Important Note: Era Tumblers are 100% leakproof with cold beverages and carbonated beverages with ice when in the locked position. Not recommended to be used in the locked position with hot beverages ConferencingWorks.
Carbonated Beverages & Air Travel
One unique advantage: the Era handles 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, slowly unlock the Ü-Turn lid to release pressure Amazon.
ColdKey™ Stainless Steel Straw System
The Era Series features the ColdKey stainless steel straw, designed to minimize plastic exposure in drinks while delivering a cool, crisp sipping experience B&H Photo Video. Unlike traditional plastic straws that can leach chemicals or retain odors, the stainless steel construction is inert, durable, and easy to clean.
The straw is topped with a SoftSip silicone tip that provides comfortable drinking without the cold shock of metal directly on lips. This thoughtful detail makes extended sipping sessions pleasant while maintaining the health benefits of minimal plastic contact.
The ColdKey straw is completely removable for cleaning. 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 Amazon. The lid mechanism can also be disassembled: turn the mode indicator halfway between the locked and open positions and pull up on the straw center piece for easy cleaning Amazon.
Performance & Insulation
Exceptional Cold Retention
Like most high-quality, stainless-steel tumblers, the Era BruMate kept ice intact for a full day, even in the heat Amazon. The BevGuard technology delivers on its promise of 24+ hour cold retention when properly used with adequate ice.
The more ice you use, the longer drinks stay cold. To maximize ice-retention, fill the Era with at least 50% ice Logitech Hub. With this ratio, beverages remain refreshingly cold throughout even the longest, hottest days.
No Condensation
The Era is triple insulated to prevent condensation from gathering on the outside of the cup, and hasn’t been seen to sweat since using it. This also makes it great for travel, as the Era won’t sweat and soak other items in travel bags or backpacks Amazon.
Hot Beverages (With Caution)
While primarily designed for cold drinks, the Era is advertised to keep drinks warm for over 8 hours, which has been found to be true Amazon. However, drinking piping-hot beverages through a straw carries scalding risk and isn’t recommended. If you need to keep a beverage warm, the Era will maintain temperature, but ensure the drink has cooled to a safe sipping temperature before drinking through the straw.
Real-World Travel & Portability
Cupholder Performance
Users with smaller-than-average car cupholders report that the 40-ounce tumbler fits comfortably within all cupholders Amazon. The tapered 3-inch base design ensures compatibility with standard vehicle, bicycle, and stroller cupholders despite the generous capacity.
Air Travel Ready
Users would absolutely travel with this tumbler on flights. The leakproof lid design is genius, and the straw is short enough at the top that it’s not going to snag on other items in bags Amazon. This eliminates the common frustration of water bottles leaking and ruining laptop bags or carry-on contents.
Gym & Active Use
The truly leakproof design makes the Era ideal for gym bags, hiking backpacks, and active lifestyles where tumblers get jostled and knocked around without consequence.
Ease of Use & Maintenance
Simple Operation
Fill, secure the lid, rotate to unlock, and sip. The Ü-Turn mechanism is intuitive after first use, requiring no instruction manual or learning curve.
Dishwasher-Safe Convenience
All parts, including the lid, are top-rack dishwasher safe with two exceptions — Dark Aura and Onyx Leopard colorways are hand-wash only for the bottle body, though lids and straws are still top-rack dishwasher safe Amazon.
The ability to completely disassemble all components ensures thorough cleaning and prevents mold or bacterial growth — a significant advantage over tumblers with non-removable straw mechanisms.
Replacement Parts
Era lids and silicone straw pieces are only interchangeable between 30oz and 40oz Era sizes, however, use the correct size stainless steel straw attachment as the 40oz straw is longer than the 30oz ConferencingWorks. Replacement parts are available through BrüMate’s website if needed over time.
