When it comes to keeping drinks at the perfect temperature, few brands are as iconic as Yeti. Their Rambler Tumblers have become a staple in many outdoor enthusiasts’ and coffee lovers’ collections, and for good reason. In this review, we’ll put the Yeti Rambler Tumbler through its paces to see if it’s worth the hype.

Design and Build

The Yeti Rambler Tumbler is available in several sizes, including 10 oz, 20 oz, 30 oz, and 36 oz. Our review unit is the 30 oz model, which features a compact design that fits perfectly in most cup holders. The tumbler’s body is made from durable stainless steel, with a double-walled insulation that provides exceptional thermal performance.

The exterior of the Rambler Tumbler features a sleek and rugged design, with a comfortable grip that makes it easy to hold onto even when wet or covered in frost. Yeti has also included a series of subtle ridges on the lid, which provide extra traction for opening and closing the tumbler.

Insulation Performance

The Rambler Tumbler’s insulation is where it truly shines. In our testing, we found that it kept drinks at an impressive temperature range of 30°F to 160°F (-1°C to 71°C) for several hours. For example:

• Ice: The tumbler kept ice intact for over 24 hours in temperatures ranging from 50°F to 80°F (10°C to 27°C).
• Hot Coffee: Our test coffee stayed hot for over 6 hours, maintaining a temperature of around 150°F (65°C) even after being left out in the open.

Lid and Spout

The Rambler Tumbler features a leak-proof lid with a spout that’s designed to make sipping easy. The lid is also dishwasher safe, making cleaning a breeze. However, we did experience some issues with the spout leaking when the tumbler was tilted at an angle.

Durability and Maintenance

The Rambler Tumbler is built to withstand the rigors of outdoor use. We subjected our test unit to repeated drops, scratches, and even exposure to extreme temperatures (from -20°F to 100°F (-29°C to 38°C)), and it showed no signs of damage.

Cleaning the tumbler is relatively easy, thanks to its smooth interior surface. However, we do recommend washing it regularly to prevent bacterial growth.

Comparison to Competitors

The Yeti Rambler Tumbler stands out from its competitors in several key areas:

• Insulation performance: The Rambler Tumbler keeps drinks at a consistent temperature for hours longer than many other insulated tumblers on the market.
• Durability: The tumbler’s stainless steel body and double-walled insulation make it incredibly resilient to damage.
• Size options: Yeti offers several size options, making the Rambler Tumbler suitable for a wide range of users.

Conclusion

The Yeti Rambler Tumbler is an exceptional product that lives up to its reputation as one of the best insulated tumblers on the market. Its impressive temperature retention capabilities, durable design, and ease of use make it a must-have for outdoor enthusiasts, coffee lovers, and anyone who values a great cup of hot or cold beverage.
