YETI Rambler 12 oz Colster Can Insulator — White, Double-Wall Vacuum Insulated with Load-and-Lock Gasket

The YETI Rambler 12 oz Colster is a rugged, double-wall vacuum insulated can cooler that keeps standard 12 oz cans and longnecks cold while protecting hands from heat and condensation.

Designed for outdoor events, tailgates and everyday use, this white YETI Colster 2.0 uses thick-gauge steel and a secure Load-and-Lock gasket to hold beverages in place and maintain chill for hours. This listing is for the Colster only — the removable stash can insert seen in some older packages is not included. Built with YETI’s Duracoat finish, the exterior resists scratching and cracking so it looks good through repeat adventures.

How does the Colster keep drinks cold for so long?

The Colster relies on a double-wall vacuum insulation barrier to slow heat transfer from ambient air into the beverage. That vacuum space dramatically reduces convection and conduction, so cold stays inside and warmth stays out.

• Double-wall vacuum insulation minimizes temperature gain.
• Thick-gauge steel improves thermal stability and durability.
• Duracoat exterior prevents cosmetic wear from regular use.

How does the Load-and-Lock gasket work and why is it useful?

The Load-and-Lock gasket creates a simple, quarter-turn seal between the Colster and a can or longneck, stabilizing the bottle or can and reducing spills. It keeps your drink upright during movement while being easy to open when you want a sip.

• Quarter-turn mechanism locks the can or bottle in place.
• Helps avoid spills during transport or at crowded events.
• Removable design makes cleanup fast and straightforward.

Will this fit my can or bottle size?

This YETI Standard Colster 2.0 is made for standard 12 oz cans and many longneck bottles; however, fit varies with shape and manufacturer. Measure your can or bottle profile if you have a nonstandard or tapered design to confirm compatibility.

• Optimized for typical 12 oz cans and common longnecks.
• Dimensions: approximately 3 in diameter by 4.25 in height.
• Some slim, tall, or oddly shaped containers may not seat fully.

How do I clean and care for my Colster?

The Colster is dishwasher-safe for everyday convenience, and the Duracoat finish reduces visible wear from normal handling. Removing the gasket before washing ensures a thorough clean and preserves the locking mechanism’s performance.

• Dishwasher-safe construction for easy cleaning.
• Remove the gasket to clean the seal and interior fully.
• Avoid abrasive cleaners to protect the Duracoat finish.

Who is this for? The YETI Rambler 12 oz Colster in white is ideal for people who spend time outside—tailgaters, campers, festival-goers and backyard hosts—who want a durable insulated holder that secures cans or longnecks and keeps beverages colder, longer. It’s also a good pick for anyone who prefers low-maintenance drinkware with a tough finish. Note: this model does not include the stash can insert that appeared with some earlier bundles; it is the Colster insulator only.
