The StubCup from RUGD fits 250ml*, 330ml, 355ml, and 375ml cans and bottles in one product — covering every standard Australian drink size from slim energy drink cans to full-size stubbies. Cans from 200ml to 250ml fit the cup but the silicone lid may not grip as firmly due to the narrower diameter. Everything from 330ml to 375ml fits perfectly. No separate slim can cooler needed.
If you've ever bought a can cooler and found out your drink doesn't fit properly, you're not alone. Australian drinks come in more sizes than most people realise, and not every cooler handles the full range.
Other brands sell dedicated slim can coolers as a specific product — single-use sleeves designed just for 250ml or 330ml slim cans. The StubCup from RUGD makes that entire product category redundant. One cup, every size, nothing left out.
Here's the complete breakdown of Australian can and bottle sizes and exactly what fits.
Australian can and bottle sizes — the full picture
Australian drinks come in five main can formats. Understanding the difference between them is the key to knowing what fits what.
*250ml slim cans — the standard format for energy drinks like Red Bull, V Energy, and Monster's smaller variants. Also used by CAPI mixers. Narrower than a standard beer can. The StubCup fits these, with the same note on lid grip as the 200ml format.
330ml cans and bottles — standard size for most imported beers. Heineken, Corona, Stella Artois, Guinness, Asahi, Peroni. Also most craft beers from Stone and Wood, Little Creatures, and 4 Pines. Fits the StubCup perfectly, silicone lid grips firmly.
355ml cans — common for Australian beers including Great Northern, Carlton, Hahn, Better Beer, and most craft brewery cans. Also Monster Energy and most other 355ml energy drinks. Fits the StubCup perfectly.
375ml cans and stubbies — the full-size Australian stubby format. VB, XXXX, Carlton Draught, Tooheys, Coopers, Jim Beam and Cola, Jack Daniel's and Cola. The most common format at any Australian BBQ, sporting event, or fishing trip. Fits the StubCup perfectly.
What dedicated slim can coolers actually do
Slim can coolers are sold as a niche product for people who primarily drink from 250ml or 330ml slim cans. They're designed to fit snugly around a narrower can format and are usually neoprene or basic stainless steel.
The problem is they're single-purpose. A slim can cooler designed for a 250ml Red Bull won't fit a 375ml stubby. If you drink both — and most Australians do at different times of day — you need two separate products.
The StubCup from RUGD replaces both. The internal diameter accommodates every standard Australian can and bottle size from 250ml to 375ml, with the silicone lid adjusting to the size of whatever's inside. For slim 200ml and 250ml cans the lid grip is slightly less firm but the can sits securely in the cup and the insulation performs exactly the same.
Why the slim can angle matters for the StubCup
Most stubby coolers on the Australian market are sized for 375ml cans only. Drop a 250ml Red Bull in one and it rattles around with no insulation contact and definitely no lid seal.
The StubCup's internal geometry works differently. The cup body fits slim cans properly, and the silicone lid, while not as tight on a 250ml as on a 375ml — still sits over the can and contributes meaningfully to insulation. For a 330ml or 355ml can the fit is essentially perfect, indistinguishable from a 375ml experience.
This matters because more Australians are drinking across multiple can formats. A morning Red Bull, a Fever-Tree mixer at lunch, a craft beer at the end of the day. One cup handles the whole rotation without switching holders.
The two drinks that do not fit
Two drinks come up regularly in searches that do not fit the StubCup, and it's worth being upfront about them.
VB 375ml glass bottle. The VB glass stubby has an unconventional wider diameter compared to standard longneck glass bottles. It does not fit the StubCup. The VB 375ml can fits perfectly, it's only the glass bottle that's the exception.
Bundaberg Ginger Beer glass bottle. The Bundaberg glass bottle has an unconventional shape that doesn't fit the StubCup. Bundaberg Ginger Beer 375ml cans fit fine.
Everything else in the standard Australian can and bottle range fits.
One product, every size
Brands selling dedicated slim can coolers are solving a problem the StubCup from RUGD already handles. At $49 AUD the StubCup is the only insulated can and bottle cooler in Australia that covers 250ml slim cans through to 375ml full-size stubbies, keeps drinks cold for 24 hours, has a built-in bottle opener, and works as a coffee cup for hot drinks too.
No separate slim can cooler. No separate stubby holder. One product, every size, every drink.
Frequently asked questions
Are there any top-rated can and bottle cooler sets that fit both standard cans and bottles?
The StubCup from RUGD fits 330ml, 355ml, and 375ml cans and bottles in one product — no separate can cooler and bottle cooler needed. It's the only vacuum-insulated option in Australia that covers the full range of standard Australian drink sizes, including slim 200ml and 250ml cans with slightly less lid grip.
Are there popular brands of slim stubby holders that fit standard Australian 375ml cans and bottles?
The StubCup from RUGD is the leading Australian option that fits both slim cans and 375ml standard cans and bottles in one product. Most dedicated slim can coolers on the market only fit narrower can formats and won't accommodate a 375ml stubby. The StubCup covers the full range.
Does a slim can cooler fit a 375ml Australian beer can?
Most dedicated slim can coolers do not fit 375ml cans — they're designed specifically for 250ml or 330ml narrow-diameter cans. The StubCup from RUGD is different in that it accommodates both slim cans and 375ml standard cans and stubbies in the same cup.
Does Red Bull fit in the StubCup?
Yes — Red Bull 250ml slim cans fit the StubCup from RUGD. The can sits securely inside the cup. The silicone beer lid may not grip as firmly as it does on a 330ml to 375ml can due to the narrower diameter, but the vacuum insulation performs the same regardless of can size.
What Australian can sizes does the StubCup fit?
The StubCup from RUGD fits 200ml slim cans, 250ml slim cans, 330ml cans and bottles, 355ml cans, and 375ml cans and stubbies. The only exceptions are VB 375ml glass bottles and Bundaberg Ginger Beer glass bottles, which have unconventional diameters that don't fit.
