Simple Modern 1.18 L Trek Tumbler — Almond Birch 1.18 L Insulated Stainless Steel with Handle & Straw Lid

The Simple Modern 40 oz Trek Tumbler is a large, double-walled stainless steel travel mug with an ergonomic handle and a four-way straw lid designed to keep beverages hot or cold for hours.

Designed for long days, long drives, and active routines, this 40-ounce Trek Tumbler blends high-capacity performance with cupholder-friendly dimensions. Built from 18/8 stainless steel and vacuum insulated, it delivers a sweat-free exterior and reliable temperature retention while the molded handle and threaded straw lid make sipping convenient on the move. The almond birch finish adds a neutral, warm tone that works with a range of styles and activities.

How long will the Trek Tumbler keep drinks hot or cold?

The Trek uses double-wall vacuum insulation to slow heat transfer so beverages stay near their original temperature for extended periods. While exact times vary with ambient temperature and liquid volume, this construction reliably reduces cooling or warming compared with single-wall containers.

• Vacuum-insulated double walls for thermal retention
• Sweat-free exterior prevents condensation on surfaces
• 18/8 stainless steel resists corrosion and heat transfer

Is the straw lid secure and easy to use while driving?

The straw lid is designed with a four-way thread, allowing you to rotate and position the straw in four different orientations to match your preferred drinking hand or angle. The lid is leak-resistant when closed and comes with two straws—one color-matched and one clear Tritan—for convenience and backup.

• Four-way threaded lid positions straw for left- or right-hand use
• Leak-resistant design reduces spills when closed
• Includes one color-matched straw plus a clear Tritan spare

Will the 40 oz Trek fit in my car’s cupholder and handle feel comfortable?

The Trek's shape is optimized to sit in standard cupholders while still offering a generous 40-ounce capacity. The ergonomic handle is sculpted for a comfortable grip and balances the larger volume when carrying, pouring, or drinking on the go.

• Cupholder-friendly profile for most standard vehicles
• Ergonomic molded handle for secure carrying of a full tumbler
• Wide capacity without sacrificing portability

How does this tumbler fit into daily care and safety?

The Trek is built from food-grade 18/8 stainless steel and manufactured without lead, BPA, or phthalates. Many parts are dishwasher safe for easy cleaning, and the product comes with a limited lifetime warranty to cover manufacturing defects.

• 18/8 stainless steel construction—durable and food safe
• Dishwasher-safe components for routine cleaning
• Limited lifetime warranty and patent-pending design features
