YETI Rambler 12 oz Colster Can Insulator — Navy, double-wall vacuum insulated, Load-and-Lock seal

The YETI Rambler 12 oz Colster in Navy is a rugged, double-wall vacuum insulated can cooler that fits standard slim and regular 12-ounce cans and keeps drinks cold without adding a can insert.

Take-your-drink confidence wherever you go: this Colster combines thick-gauge stainless steel, YETI’s signature Duracoat finish, and a Load-and-Lock gasket to deliver lasting temperature retention and a secure seal. It’s designed for outdoor adventures, backyard hangs, and everyday use when you want condensation-free cans that stay colder longer and look great doing it.

How does the Colster keep a can cold for longer?

The Rambler Colster uses double-wall vacuum insulation to dramatically slow heat transfer, so cold from the beverage isn’t lost to the surrounding air. The thick stainless-steel shell adds thermal mass and durability while preventing condensation on the outside.

• Double-wall vacuum insulation reduces heat exchange.
• Thick-gauge stainless steel holds temperature and resists dents.
• Duracoat finish protects color and resists chipping outdoors.

Will it fit my can, and how does the seal work without a can insert?

This model is made for standard 12 oz cans—slim and regular profiles—without requiring a separate inner sleeve. The Load-and-Lock gasket secures the can with a simple quarter-turn, holding it snugly in place to stop wobble and minimize air exposure.

• Compatible with most 12 oz slim and standard cans.
• Load-and-Lock gasket uses a quick quarter-turn to lock the can.
• No separate can insert necessary, reducing extra parts and bulk.

How tough is the finish and construction for outdoor use?

Built from YETI’s thick-gauge steel, the Colster is engineered to withstand rough handling and outdoor conditions. Duracoat color covers the exterior to resist cracking, fading, and chipping so it stays looking new through seasons of use.

• Thick-gauge stainless steel for impact resistance and longevity.
• Duracoat powder coat resists chips and UV fading.
• Simple design means fewer failure points during heavy use.

How easy is the Colster to clean and carry?

Maintenance is straightforward: hand wash recommended to preserve the Duracoat finish and gasket. The compact, lightweight design fits cup holders and stashes easily in a bag, while the secure gasket prevents leaks during transport.

• Hand wash to protect finish and gasket integrity.
• Compact shape fits most cup holders and cooler pockets.
• Load-and-Lock reduces spills while carrying or moving.

Who this is for: If you regularly bring canned drinks to picnics, tailgates, fishing trips, or backyard gatherings and want a no-fuss solution that keeps beverages cold and condensation-free, the YETI Rambler 12 oz Colster in Navy is built for you. It’s a good match for people who prefer rugged, low-maintenance gear, value proven insulation, and want a stylish, durable finish that holds up to outdoor life.
