BrüMate Era 40 oz Tumbler — Electric Blue leakproof insulated water bottle with handle & straw, 24+ hour cold retention

The BrüMate Era 40 oz is a stainless steel, fully leakproof straw tumbler designed to keep cold drinks icy for 24+ hours while fitting most cup holders and everyday carry.

Built for people who want a large-capacity, travel-friendly drink container without spills, the Era blends a tapered, cup-holder-friendly form with a patent-pending Ü-Turn lid system that prevents leaks even with carbonated beverages. Made from durable stainless steel with BevGuard insulation and a ColdKey metal straw, this 40-ounce tumbler adds convenience with a soft-touch handle, top-rack dishwasher safety, and a lifetime warranty for long-term use.

How does the Era prevent leaks when carried in a bag?

The Era uses BrüMate’s patent-pending Ü-Turn technology in the lid to create an internal flow path that closes when not in use, blocking liquid escape. This mechanism is engineered to handle both still and carbonated drinks without pressure-related seepage.

• Ü-Turn valve closes the straw channel when idle
• Secure screw-on lid compresses to form a tight seal
• Tested for movement and pressure with carbonated beverages

What keeps drinks cold for more than a day?

BevGuard insulation pairs a double-wall vacuum with thermal barriers to limit heat transfer, so ice and cold temperatures last for 24+ hours. The stainless steel body also resists sweating, keeping exterior surfaces comfortable to handle and preventing condensation rings.

• Double-wall vacuum construction reduces heat exchange
• Stainless-steel interior preserves flavor and coolness
• Exterior stays dry—no condensation on surfaces

Is the 40 oz Era practical for daily use and cleaning?

The Era’s tapered silhouette slides into most standard car cup holders and the handle gives a confident grip while on the move. For upkeep, the body, lid, and ColdKey metal straw are all top-rack dishwasher safe, making maintenance straightforward.

• Tapered shape fits most vehicle and stroller cup holders
• Comfortable soft-touch handle for one-handed carry
• Top-rack dishwasher safe components for easy cleaning

What extras come with the Era and how durable is it?

The Era includes BrüMate’s ColdKey stainless steel straw with a soft silicone tip to reduce plastic use and improve the drinking feel. Built from high-grade stainless steel and backed by a lifetime warranty, the tumbler is intended to withstand daily bumps and regular use.

• ColdKey metal straw with silicone tip for a cooler sip
• Lifetime warranty covering manufacturing defects
• Designed to resist dents and maintain insulation over time

Who this is for: The BrüMate Era 40 oz suits commuters, gym-goers, parents, and anyone who prefers a single, large-capacity vessel for water, iced beverages, or carbonated drinks while on the move. It’s ideal for people who want leakproof confidence in a cup-holder-friendly size, low-maintenance cleaning, and an insulated bottle that keeps drinks cold all day.
