YETI Rambler 16 oz. Colster Tall Can Insulator — Harvest Red, Vacuum-Insulated & Load-and-Lock

The YETI Rambler 16 oz. Colster Tall Can Insulator in Harvest Red is a double-wall, vacuum-insulated sleeve that keeps tallboys and 16 oz cans cold and sweat-free for hours.

Whether you’re tailgating, camping, or just relaxing on the patio, this insulated Colster is built to hold 16 oz cans and tallboys securely while preserving chill and preventing condensation. Constructed from thick-gauge stainless steel with a durable Duracoat finish, the Rambler Colster resists dings and retains its color. The Load-and-Lock gasket seals with a quarter-turn to hold cans in place, and the dishwasher-safe design makes cleanup simple.

How well does the Colster keep a tall can cold?

The vacuum-insulated double-wall design reduces heat transfer so your beverage stays cold longer than an uninsulated can or thin sleeve. It’s designed to reduce warming from hand heat and ambient temperatures during typical outdoor activities.

• Double-wall vacuum insulation minimizes heat exchange
• Thick-gauge steel resists temperature transfer from contact
• Duracoat finish stops surface sweating and provides grip
• Ideal for multi-hour events like game days, BBQs, and concerts

Will my 16 oz tallboy or longneck fit securely?

The Colster is made to accommodate most 16 oz tall cans, tallboys, and many longneck bottles, though fit can vary by shape and taper. The Load-and-Lock gasket locks the can in place with a simple quarter-turn, keeping it stable during movement and on uneven surfaces.

• Designed for 16 oz cans and many tallboys
• Quarter-turn Load-and-Lock gasket secures the beverage
• Compatibility varies slightly by can or bottle shape
• Measures approximately 3 in × 6 in for scale reference

Is the Rambler Colster durable and easy to maintain?

Yes — YETI built this Colster from thick-gauge stainless steel with a chip-resistant Duracoat so it holds up to outdoor use. When the day is done, the Colster is dishwasher safe for straightforward cleaning, and the rugged construction minimizes dents and wear.

• Thick-gauge stainless steel for strength and impact resistance
• Duracoat color finish resists chipping and fading
• Dishwasher safe for convenient cleanup
• Load-and-Lock gasket designed for repeated use

Colster Tall Can Insulator in Harvest Red is ideal for people who take drinks outdoors often — tailgaters, campers, backyard hosts, and festival-goers who want a sturdy, no-fuss way to keep tall cans cold and hands dry.
