Frost Buddy Universal Can Cooler — Fits All Standard and Slim Cans

The Verdict

The Frost Buddy Universal Can Cooler solves the problem that insulated cup owners eventually face: your Yeti is great for your coffee, but what about the beer at the barbecue? What about the seltzer at the beach? What about the slim can your spouse brought home? This single cooler handles all of them.

The Universal Claim, Tested

Frost Buddy claims to fit five sizes in one: standard 12oz cans, slim 12oz cans, 16oz cans, standard bottles, and even wine bottles. The magic comes from a removable silicone insert that adapts the interior diameter. Leave it in for slim cans, pull it out for bottles.

“Really does fit almost everything!!” one reviewer exclaims. “It’s not too bulky, it fits in all my cup holders, keeps my drinks cold even when they are sitting in the SUN!!”

Another reviewer who bought a second one for their spouse confirms: “Excellent product! Keeps everything cold, and yes all the different sized cans and bottles fit great.”

The insulation performance is genuinely impressive. The double-wall vacuum construction keeps drinks cold for well over 24 hours — useful for beach days, fishing trips, or just not wanting to get up from the couch mid-game.

No More Can Sweat

One of the most underrated features is the condensation elimination. Anyone who has grabbed a cold beer from a cooler only to have water drip down their arm knows the annoyance. The Frost Buddy exterior stays completely dry.

“Love these!” writes a reviewer who uses them at work and home. “It keeps the can chilled — and no messy dripping from can sweat. Also used at home for thin can beverages. This is my second one personally so I can leave one at work.”

The textured bottom provides serious grip on tables, preventing the annoying tip-over that happens with bare cans. The lid fits tightly across a variety of drink sizes, and the overall build quality matches what you’d expect from the $50 price bracket.

The Catch

The optional drinking lid — which transforms the cooler into a full travel mug — is sold separately. At $51.64, it feels like an oversight not to include it. Some users also note that the insert piece for 12oz cans is small enough to lose in a drawer or beach bag.

“I’m not a fan of, even though there isn’t really a way around it, is that you have to put the little insert piece in to fit 12oz cans,” someone notes candidly.

One detailed reviewer gives 3.5 stars for what they consider minor annoyances: “If you are looking for an honest review… it’s a solid product, just understand the limitations going in. The fit on taller bottles is snug, and if you want the full mug experience, budget another $10 for the lid.”

The Verdict

The Frost Buddy Universal Can Cooler is the most versatile insulated can cooler on the market. If you drink multiple types of canned or bottled beverages — or if your household does — the universal fit saves you from buying a dozen single-purpose koozies. It keeps drinks cold, your hands dry, and fits in your cup holder. Buy it, keep track of the insert, and your drinks will stay cold from the first pitch to the ninth inning.
