Most can coolers commit you to a single shape. DUALIE is a vacuum insulated 304 stainless sleeve with a swap cap system, so the same body takes a standard 12 oz can, a tall slim can or a 12 oz bottle, and changes over in a couple of seconds.

Each model starts from the same insulated sleeve and adds one job on top of it. Pick by what you drink, then pick a color.
Every model in the range is built around the same question: what is in your hand, and what else do you want the cup to do while you hold it. Answer both and the match appears below.

Some colors run across every model, others only exist on one. The swatch takes you to the model that carries it.
A can cooler is a simple object with one awkward problem: drink cans are not one shape. A standard 12 oz can is short and wide, a tall slim can is narrow and long, and a 12 oz bottle is a different profile again. Buy a sleeve molded for one of them and the other two rattle or will not go in at all. That is why most people end up with a drawer of mismatched coolers and grab whichever one fits whatever came out of the fridge.
DUALIE answers it with a patent pending cap system. The body stays the same, the cap changes, and the seal moves to meet the container in your hand. Dual wall vacuum insulation keeps the cold in and the condensation off your palm, so the outside stays dry and does not leave rings on a table. The shell is 304 stainless with a powder coated finish that resists chips, and the whole thing goes in the dishwasher when the weekend is over.
The Lower Deckie keeps the cooler and adds a twist off metal tin in the base, sized for a standard pack of pouches, so the thing you were already carrying rides in the cup instead of your pocket. The Tracker wraps a turning ring around the body with numbers on it, which started as a way to keep score at cornhole and ended up being just as useful for remembering how many you have had. The hip flasks step away from cans altogether: clear Tritan, no metal anywhere, a silicone bumper around the body, in six and eight ounces.
Everything on this site is the current DUALIE catalog with live pricing from the retail listing. Each color has its own page because the finishes genuinely behave differently in the sun, in a cup holder and in a bag.
