Simple Modern 1.18 L Trek Tumbler Travel Mug — Midnight Black, Insulated Stainless Steel with Handle & Straw Lid

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

Designed for long days on the road, at work, or on outdoor adventures, this Trek tumbler pairs robust insulation with user-focused features: an ergonomic handle for comfortable carrying, a leak-resistant straw lid with four drinking positions, and a sweat-free exterior that won’t sweat on your surfaces. Built from 18/8 stainless steel and offered in a striking Midnight Black finish, the 40 oz capacity holds large pours while still fitting most standard cup holders.

How does the insulation keep beverages at the right temperature?

The Trek uses double-wall vacuum insulation to reduce heat transfer, so hot drinks stay warm and cold beverages stay chilled longer than single-wall cups. The sealed design also prevents exterior condensation, keeping the outside dry and comfortable to hold.

• Double-wall vacuum barrier minimizes heat exchange
• Sweat-free exterior avoids condensation rings on surfaces
• Stainless steel construction retains temperature without flavor carryover

What makes the handle and lid user-friendly for daily use?

The ergonomically contoured handle is shaped for a secure, comfortable grip when carrying a full 40 oz container. The straw lid is four-way threaded so you can rotate it to the most convenient orientation for either hand, and it includes two straws—one color-matched and one clear Tritan—for immediate use or easy replacement.

• Comfort-shaped handle designed for steady, one-handed transport
• Four-way threaded lid allows four straw placement options
• Two straws included: matching and clear Tritan for durability

Will this fit in my car’s cup holder and survive everyday wear?

The tapered base is engineered to sit in most standard cup holders, making it convenient for commuting or road trips. Constructed from 18/8 stainless steel and finished with a resilient coating, the tumbler resists dents and maintains appearance through regular use.

• Tapered profile fits standard cup holders in most vehicles
• Durable 18/8 stainless steel resists corrosion and flavors
• Dishwasher-safe components simplify cleaning (follow care guidance)

How does this tumbler support safety and product longevity?

Materials are free from lead, BPA, and phthalates, and the construction is backed by a limited lifetime warranty to protect against manufacturing defects. The leak-resistant lid helps reduce spills while the sturdy build is meant to last through daily use.

• Made without lead, BPA, and phthalates for safer sipping
• Leak-resistant insulated lid reduces accidental spills
• Limited lifetime warranty and patent-pending features for peace of mind

Who this is for: The Simple Modern 40 oz Trek Tumbler is aimed at commuters, outdoor enthusiasts, busy parents, and anyone who prefers a large-capacity drink container that stays temperature-stable and fits into a cup holder. If you want a durable, no-fuss travel mug with an ergonomic handle, flexible straw lid options, and a sweat-free exterior, this tumbler is a practical everyday companion.
