BrüMate Era 40 oz Insulated Tumbler — Matte Black, Leakproof Lid & SoftSip Straw

The BrüMate Era 40 oz is a stainless-steel, fully leakproof insulated tumbler with a soft-touch straw and handle, built to keep drinks cold for 24+ hours and travel without spills.

The BrüMate Era combines a large-capacity 40 oz vessel with patented leakproof engineering and a comfortable carry handle. Designed for active days, commutes, and long outings, this matte black tumbler pairs a durable stainless-steel body with a SoftSip straw tip and a removable lid that fits most cup holders. Its insulation system preserves chill while the ColdKey metal straw reduces single-use plastic contact.

How does the Era stay leakproof when tilted or stored in bags?

The Era uses BrüMate’s patent-pending Ü-Turn mechanism integrated into the lid, creating a secure barrier between the straw opening and the rest of the lid. That design prevents accidental spills even with carbonated liquids, so you can toss the tumbler into a backpack or the trunk without worrying about messes.

• Patent-pending Ü-Turn lid seals straw pathway.
• Engineered for both still and carbonated beverages.
• Hard-wearing lid components resist wear from daily use.

What keeps drinks cold for more than a day?

BevGuard insulation inside the double-wall stainless-steel body minimizes heat transfer, so ice and chilled beverages maintain temperature far longer than single-wall options. The thick insulation plus a tight-fitting lid reduces air exchange and slows melting, delivering sustained cold across long outings.

• Double-wall stainless steel with BevGuard insulation.
• Large 40 oz capacity lowers refill frequency.
• Secure lid minimizes warm-air intrusion.

Is the Era easy to clean and commute-friendly?

The Era is designed for everyday convenience: most bodies are dishwasher safe while lids and the ColdKey straw are safe on the top rack. Its tapered profile fits standard cup holders and the ergonomic handle makes carrying a full 40 ounces comfortable on the move.

• Top-rack dishwasher safe lids and straws.
• Sleek, tapered shape fits most cup holders.
• Handle provides stable, comfortable transport.

What materials and warranty protections come with this tumbler?

Constructed from high-grade stainless steel, the Era replaces single-use plastics with a reusable ColdKey metal straw and a SoftSip silicone tip. BrüMate stands behind the build with a lifetime warranty that covers manufacturing defects, so the tumbler is meant to last through daily use and travel.

• Durable stainless-steel body and ColdKey straw.
• SoftSip silicone tip for comfortable sipping.
• Lifetime warranty against defects in materials and workmanship.
