BrüMate Era 40 oz Tumbler — Nightfall Blue insulated stainless steel, handle & leakproof lid

The BrüMate Era 40 oz Tumbler (Nightfall Blue) is a fully leakproof, double‑walled stainless steel bottle with a handle and SoftSip straw designed to keep drinks cold for 24+ hours and travel mess‑free.

If you want a large, cup‑holder friendly tumbler that tolerates carbonated drinks, fits in most cup slots, and survives daily use, the Era combines patent‑pending leakproof technology, BevGuard insulation, and a stainless steel ColdKey straw with a soft silicone tip. It’s built for commuting, workouts, long shifts, or days when refills are inconvenient — all while minimizing spills and plastic contact with your beverage.

How does the Era stay 100% leakproof with a straw?

The Era uses BrüMate’s Ü‑Turn sealing system in the lid, which channels liquid away from seams and prevents leaks even when the tumbler is tilted or jostled. That makes it safe to carry in bags or backpacks without protective covers.

• Patent‑pending Ü‑Turn valve architecture routes liquid to a secure exit.
• Precision molded lid parts create a tight barrier around the straw opening.
• Designed for both still and carbonated beverages without pressure loss.

Will my drinks stay cold for an entire day?

The Era employs BevGuard double‑wall vacuum insulation to maintain low temperatures for 24+ hours, so ice and chilled beverages last far longer than in single‑wall bottles. That insulation also reduces condensation, keeping your hands and surfaces dry.

• BevGuard vacuum insulation minimizes heat transfer.
• Double‑wall stainless steel body prevents exterior sweat marks.
• Ideal for long commutes, outdoor activities, or all‑day office use.

Is the Era convenient to use and clean every day?

The tumbler’s tapered silhouette is cup‑holder friendly and the integrated handle makes carrying a full 40 oz simple. Most bodies are dishwasher safe; lids and straws are designed for top‑rack cleaning so you can refresh the parts without special tools.

• Sleek tapered design fits standard vehicle and stroller cup holders.
• ColdKey stainless steel straw with SoftSip silicone tip reduces plastic contact.
• Top‑rack dishwasher safe lids and straws; many bodies safe for dishwasher cycles.

What extras protect my purchase and improve sustainability?

BrüMate backs the Era with a lifetime warranty, and the reusable ColdKey straw plus a durable stainless steel body reduce single‑use plastic dependence. The SoftSip tip increases comfort while avoiding disposable mouthpieces.

• Lifetime warranty for long‑term durability and service.
• ColdKey metal straw lowers single‑use plastic consumption.
• Hardy stainless steel construction extends product lifespan.

Who is this for? The BrüMate Era 40 oz Tumbler in Nightfall Blue suits anyone who drinks large volumes on the go — commuters, parents, fitness enthusiasts, outdoor lovers, and professionals who need spillproof performance. Choose the Era if you want a travel‑friendly, cup‑holder compatible, and sustainable tumbler that keeps beverages cold all day and eliminates leaks while carrying carbonated or still drinks.
