**Short answer: they're the same thing.** A koozie (also spelled coozie or cozy, and called a "can cooler" in the promotional-products industry) is an insulated sleeve that slips over a canned drink to keep it cold and your hand dry. The different names are just spelling variants of the same product — there is no functional difference.

## Where did the word "koozie" come from?

"Koozie" began as a trademarked brand name for foam can insulators in the early 1980s, and like Kleenex or Band-Aid, the brand name became the everyday word for the whole category. Today "koozie" (with a K) is by far the most common spelling people type into Google — even though, strictly speaking, it still refers to one specific brand.

## So what's a "coozie"?

"Coozie" is the most popular generic respelling — same pronunciation, no trademark baggage. You'll also see "cozy" (borrowed from the British "tea cosy," the knitted cover that keeps a teapot warm), "kozie," and "huggie" in some parts of the South. They all describe the same insulated sleeve.

## Why do catalogs say "can cooler"?

Promotional-product suppliers and big-box retailers usually list the product as a "can cooler" or "can insulator" precisely because "Koozie" is trademarked. If you're searching a wholesale catalog and can't find koozies, try "can cooler" — it's the industry's official-sounding name for the exact same item.

## Which name should you use?

Whichever you like — everyone will know what you mean. If you're searching online, "koozie" returns the most results, and "custom can coolers" surfaces the wholesale suppliers. At Reel48 we spell it *koozie*, since that's what most people search for, but our [online designer](https://www.reel48.com/design/coozie) doesn't care what you call it: pick a color, add your logo, and order a [custom koozie](https://www.reel48.com/products/custom-coozie) with transparent volume pricing either way.

## Does the name change the product?

No — but the *material* does. Whatever you call them, drink sleeves come mainly in neoprene (the stretchy wetsuit fabric we use) and collapsible foam. The material affects insulation, print quality, and durability far more than the spelling ever will; we break that down in our [neoprene vs. foam guide](https://www.reel48.com/blog/neoprene-vs-foam-koozies).
