50 oz Mug Tumbler with Handle and Straw Lid - Large Insulated Travel

In this review the Simple Modern Trek 50 oz mug tumbler proves itself as a practical choice for anyone who needs a large, durable bottle for long days away from home. The single biggest reason to buy is its combination of a true 50oz capacity and reliable double wall insulation, which means fewer refills and drinks that stay cold or hot for hours. The ergonomic handle and straw lid make it easy to sip while on the move, and the build quality feels noticeably solid compared with similar large tumblers.

Key Features

• 50 oz Capacity: A large internal volume reduces the need to refill, ideal for long workdays, workouts, or travel.
• Double Wall Insulation: Vacuum insulated walls maintain beverage temperature for hours so ice lasts and hot drinks stay warm.
• Straw Lid with Four-Way Threading: The included straw lid can be positioned in four different places to suit left- or right-handed drinking preferences.
• Ergonomic Handle: A sculpted handle provides a comfortable grip for carrying a full 50 oz jug without strain.
• 18/8 Stainless Steel Construction: Durable, food-grade metal resists dents and keeps flavors neutral over repeated use.
• Leak Resistant Design: The straw lid helps prevent spills when closed, making it practical for commuting and car travel.

Who It's For

The Trek 50 oz tumbler is best for people who want a high-capacity, insulated bottle to cut down on refills: commuters, field workers, parents, and gym-goers will appreciate the size and the insulating performance. The handle and straw lid suit users who prefer sipping over tilting a cup, and the bottle fits most standard cupholders for easy transport.

This is not the ideal choice for someone who needs an ultralight packable bottle for backpacking or minimalists who prefer compact gear; the 50 oz capacity and sturdy 18/8 stainless steel make it heavier and bulkier than slim travel bottles.
