YETI Rambler 20 oz Stainless Steel Tumbler - Keeps Drinks Hot or Cold

In this review the YETI Rambler 20 oz stainless steel tumbler stands out as a durable everyday insulated cup for people who demand temperature retention and low maintenance. The single biggest reason to buy is its double-wall vacuum insulation, which reliably preserves hot coffee or iced beverages for hours. The review finds the tumbler particularly well suited to commuters, outdoor users, and anyone who dislikes condensation on their hands, while noting the magnetic lid is convenient but not a substitute for a leakproof cap.

Key Features

• Durable stainless steel: The solid construction resists dents and stands up to daily use without compromising insulation.
• Double-wall vacuum insulation: Keeps hot drinks hot and cold drinks cold for extended periods so you can enjoy the intended temperature longer.
• MagSlider Lid: A magnetic slider provides an easy open and close action that helps limit heat or cold loss during normal use.
• No Sweat Design: Exterior stays dry so it is comfortable to hold and prevents water rings on tables.
• Dishwasher safe and BPA-free: Simple to clean and safe for everyday use, saving time on maintenance.
• Sized for cup holders: At about 6 7/8 in high it fits in standard cup holders for travel convenience.

Who It's For

The Rambler 20 oz is ideal for commuters, hikers, or anyone who wants a sturdy insulated tumbler that fits most vehicle cup holders and keeps beverages at serving temperature. Its tough Duracoat options also appeal to those who want color that lasts without peeling or fading.

People who need a fully leakproof bottle for backpacks or tilting travel should look elsewhere, since the MagSlider Lid is handy but not designed to prevent spills. Buyers who prefer ultra-lightweight single-use cups may also find the stainless steel weight unnecessary.
