Simple Modern Trek 40oz Tumbler with Handle & Straw — Checkered, Double-Wall Vacuum Insulated

The Simple Modern Trek 40oz Checkered is an insulated stainless steel tumbler with a comfortable handle and straw lid built for spill-resistant, all-day hydration.

Designed to move with your routine, this 40oz Trek pairs durable 18/8 stainless steel construction with double-wall vacuum insulation, a molded handle for one-handed carrying, and a straw lid to reduce spills while you commute, work, or exercise. It fits most cupholders and is sized to support long days between refills. The Checkered finish adds a modern, textured look so your bottle stands out on a desk or in a gym bag.

How well does the Trek keep drinks cold or hot?

The Trek uses double-wall vacuum insulation to slow heat transfer, so cold drinks stay chilled and hot drinks hold temperature longer than single-wall containers. While exact hours vary with conditions and contents, the insulation preserves flavor from the first sip to the last.

• Double-wall vacuum design reduces condensation and temperature loss.
• Stainless interior resists flavor transfer and staining.
• Works equally well with water, iced tea, coffee, and infused beverages.

Does the handle and straw lid make it practical for daily use?

The molded handle allows secure one-handed carrying and is shaped to slide onto straps or hooks for short-term hands-free transport. The straw lid lowers the chance of splashes when moving between locations, and its components are dishwasher-safe for easy care.

• Ergonomic handle for carrying, handing off, or hooking to bags.
• Straw lid reduces spills while walking or driving.
• Removable lid and straw are dishwasher-safe for quick cleaning.

Will the 40oz size fit in my car or bag cupholder?

The Trek is engineered to fit most standard cupholders found in cars and many backpacks, making it a practical option for commuters. Its tall profile holds more liquid for longer outings while remaining balanced and portable.

• Slim enough at the base for most cupholders, wide enough for a steady grip.
• 40oz capacity reduces the need for frequent refills during busy days.
• Compact enough to sit on a desk without overcrowding your workspace.

How durable and safe is the material?

The Trek's interior uses food-grade 304 (18/8) stainless steel, which resists corrosion and won’t leach BPA, lead, or phthalates. The exterior finish is built for everyday bumps, and the insulated body is intended for long-term use when cared for according to washing instructions.

• 18/8 stainless steel interior for longevity and neutral taste.
• Exterior retains finish through everyday handling and transport.
• Refer to the product base for specific dishwasher-safety guidance.

Who this fits: the Simple Modern Trek 40oz Checkered is ideal for busy commuters, gym-goers, students, and parents who want a single container that’s easy to carry, reduces splashes, and holds enough fluid to last through long shifts or workouts. It’s also a practical, gift-ready choice for birthdays and holidays, and pairs visually with other Simple Modern pieces for coordinated sets.
