Simple Modern 40oz Ceramic-Lined Tumbler with Handle — Checkered, Leak-Proof Straw Lid

The Simple Modern 40oz Signature Trek is a ceramic-lined, double-wall insulated tumbler with a leak-proof push-to-lock straw lid and a comfortable handle for all-day hydration.

Designed to combine taste-preserving materials with day-to-day durability, this 40oz Signature Trek tumbler pairs a ceramic-lined interior with 18/8 stainless steel insulation and a four-way threaded silicone straw. The push-to-lock lid system seals the straw down for spill-free transport, while the tapered shape fits most standard cupholders. Built for commutes, workouts, and long days out, the Signature Trek keeps beverages tasting fresh and stays easy to carry thanks to an ergonomically placed handle and a grippy silicone base.

How does the ceramic lining affect drink taste and temperature?

The ceramic lining creates a neutral surface that helps prevent metallic or lingering flavors from altering your coffee, tea, or water. Combined with double-wall vacuum insulation, the tumbler maintains hot or cold temperatures for extended periods without transferring flavors.

• Ceramic-lined interior for cleaner flavor retention
• Double-wall vacuum insulation to preserve temperature
• 304 (18/8) stainless steel body for safe, durable construction
• Suitable for hot and cold beverages without aftertaste

Is the lid truly leak-proof for travel and bags?

The push-to-lock silicone straw lid locks the straw down to create a secure seal, letting you toss the tumbler into a gym bag or backpack with confidence. When unlocked, the straw pulls up for easy sipping; push it down and it snaps into a locked position to reduce spills.

• Push-to-lock mechanism secures the straw when closed
• Silicone components help create a tight seal against leaks
• Threaded straw allows angle adjustment for comfortable drinking
• Top-rack dishwasher safe lid components for easy cleaning

What features make this tumbler comfortable and stable to use?

An easy-grip handle provides single-handed carrying without awkward balancing, and a soft silicone base cushions contact with surfaces to reduce clatter and slipping. The tapered design fits most standard car cupholders for convenient in-vehicle use.

• Ergonomic handle for one-handed carrying
• Silicone base for added stability on desks and consoles
• Tapered shape that fits most cupholders for travel convenience
• Durable finish designed for daily use and commutes

How do I care for the Signature Trek to keep it working and looking its best?

The straw lid and inner straw are top-rack dishwasher safe for straightforward cleaning; check the base of your color variant for any specific care notes. For longevity, rinse and dry the ceramic-lined interior after use and periodically clean the lid assembly to prevent buildup around the locking mechanism.

• Top-rack dishwasher safe for lid and inner straw pieces
• Wipe or hand-wash the exterior to preserve finish when needed
• Inspect the base for color-specific care instructions
• Disassemble the lid for occasional detailed cleaning of seals
