YETI Rambler Colster Can Insulator, Black — Fits 12 oz Cans, Double-Wall Vacuum Insulation

The YETI Black Rambler Colster Can Insulator is a rugged, double-wall vacuum sleeve that seals onto standard 12 oz cans and longnecks to keep drinks cold longer.

Whether you’re at a backyard barbecue, tailgate, or out in the heat, the YETI Rambler Colster is built to maintain beverage temperature and withstand rough use. It combines YETI’s thick-gauge steel construction with a quarter-turn Load-and-Lock gasket and a durable Duracoat finish, delivering reliable insulation and an easy-to-use seal. Dimensions fit most standard cans and many bottles, though exact fit depends on bottle shape.

How does the Colster keep drinks colder compared with a bare can?

The Colster uses a double-wall vacuum barrier to slow heat transfer from warm air into your drink, so cooling lasts far longer than an exposed can. The metal body also reduces condensation, keeping hands dry and surfaces clean. Its thick-gauge steel adds durability, resisting dents and warping.

• Double-wall vacuum insulation reduces heat gain.
• Thick-gauge steel improves longevity and impact resistance.
• Duracoat finish resists chipping and keeps appearance intact.

What makes the Load-and-Lock gasket practical for parties and outings?

The Load-and-Lock gasket seals with a simple quarter-turn, giving a secure hold that prevents the can from popping out during movement. It’s designed for quick loading and unloading so you can switch cans fast. The sealed connection also minimizes chilled-air loss when you’re not drinking.

• Quarter-turn gasket locks cans in place quickly.
• Reduces cold air escape between sips.
• Simple disassembly for cleaning and dishwasher-safe convenience.

Will my bottle or longneck fit this Colster?

The Rambler Colster is optimized for standard 12 oz cans and many longneck bottles, but compatibility can vary with unusual neck or shoulder shapes. It’s best for traditional cylindrical cans and most common bottle silhouettes. Check measurements if you use oversized or uniquely shaped bottles regularly.

• Designed primarily for 12 oz cans and many longnecks.
• Fit depends on bottle shoulder and neck profile.
• Measures approximately 3 inches by 4.25 inches for quick reference.

How do I care for and clean the Colster?

The Colster is user-friendly when it comes to maintenance: it’s dishwasher-safe, and the gasket can be removed for a thorough rinse. The Duracoat exterior holds up to scrubbing without flaking, and the steel interior resists stains. For best performance, let parts dry completely before reassembly.

• Dishwasher-safe for easy cleaning.
• Remove gasket to clean the seal area thoroughly.
• Duracoat resists chipping and fading over time.

Who is this for? The YETI Black Rambler Colster is aimed at people who want their canned drinks to stay cold during outdoor events, long afternoons, or active days—campers, tailgaters, grillers, and anyone who values durable drinkware. It’s also a solid choice for those who prefer low-maintenance gear that won’t show wear from regular use.
