The YETI Rambler 12 oz. Colster Slim Can Insulator is designed specifically for slim cans, making it an excellent choice for those who enjoy spiked seltzers, canned wine, and other similar beverages. The standout feature is its double-wall vacuum insulation that keeps drinks very cold, which is perfect for beach days and cabin weekends. With a simple quarter-turn Load-and-Lock gasket, securing your can is quick and easy.

The stainless steel construction, combined with YETI's signature Thick Gauge Steel, ensures that this Colster is both strong and durable, withstanding the rigors of outdoor adventures. The Duracoat color finish prevents cracking and chipping, maintaining its appearance over time. Also, it's dishwasher safe, making cleanup a breeze.

However, it's worth noting that this version does not include the Stash Can, which might be a drawback for some users who found that feature useful. Measuring 2.25 inches in diameter and 6 inches in height, it fits easily into most cup holders.

Users appreciate that this cooler is easy to use - you simply push your can into the holder, and a Push-Lock Gasket keeps it securely in place.

However, it might be bulkier compared to standard koozies, given its dimensions (3.14 x 3.14 x 6.13 inches) and weight (1.24 pounds). Additionally, it requires hand washing, which might be a minor inconvenience for some users. Nevertheless, with a high customer rating of 4.7 out of 5 stars from over 20,000 reviews, it is highly regarded for its performance and design. This product is particularly suitable for those who enjoy cold beverages on the go and appreciate multifunctional tools in their daily routines.
