Insulated drinkware splits into two jobs. A can cooler wraps a can or bottle you already have; a tumbler holds a drink you pour in. Several products now try to do both, which is where most of the real differences hide: which can sizes fit, whether a lid turns it into a sealed cup, and what the warranty says about dishwashers and freezers.
We compared five popular picks using each brand's own product and policy pages, checked on Oct 27, 2026. Search Wary did not test these hands-on, so every cold-hold number below is the brand's own claim, measured by the brand in conditions it doesn't always spell out.
Frost Buddy's Universal Buddy is our top pick, followed by four alternatives that suit people who only drink standard cans, prefer 16 oz tallboys, want a 40 oz water tumbler or need a sealed coffee cup.
Our top pick
Frost Buddy Universal Buddy
The Universal Buddy is the only pick here that Frost Buddy says fits standard 12 oz cans, slim cans, 12 oz bottles and 16 oz cans in one sleeve, so one cooler covers almost anything in the fridge. At $39.99 for solid colors, with some designs on sale from $19.99, it also comes with free US shipping on orders over $70 and a 30-day return window.

Best overall can cooler
1. Frost Buddy Universal Buddy
$39.99 (sale designs from $19.99)
Frost Buddy calls the Universal Buddy the first can cooler built to fit every common can size. Per the brand, it takes 12 oz standard cans, 12 oz slim cans, 12 oz bottles and stubby bottles, and 16 oz cans and bottles, which means no separate slim-can sleeve for seltzers.
It's double-walled stainless steel, 6.3 by 2.9 inches, and Frost Buddy says it keeps drinks cold for 12+ hours and hot for 6+ hours. An optional coffee lid, which the brand describes as leak-proof, turns it into a 16 oz tumbler. It's cup-holder compatible, and Frost Buddy recommends hand washing.
Solid colors such as Navy were $39.99, licensed sports designs $44.99, and a handful of patterns were marked down to $19.99 to $27.99 on Frost Buddy's site. Free US shipping starts at $70, and the bundle builder takes 10% to 15% off multiples. Returns are accepted for 30 days on unused items.

Best for standard 12 oz cans
2. YETI Rambler 12 oz Colster Can Cooler
$30
The Colster is a single-purpose can cooler done carefully. YETI uses double-wall vacuum insulation, a No Sweat design to keep the outside dry, and a quick-turn gasket that locks the can in place. It's dishwasher safe and, per YETI, fits most cup holders.
The 12 oz Colster was $30 on YETI's site. It fits standard 12 oz cans only; YETI sells the 16 oz Tall Colster separately at $35, and slim cans need their own model. YETI doesn't publish an hours-cold figure on the product page, saying only that it keeps drinks cold until the last sip.
Where YETI stands out is support: Rambler drinkware carries a 5-year warranty, returns are free, and shipping is free for account holders. If you only drink standard cans and want the sturdiest-feeling option with a clear warranty, this is it.
- Fits
- 12 oz standard cans
- Insulation
- Double-wall vacuum
- Cold claim
- No hour figure published
- Cleaning
- Dishwasher safe
- Warranty
- 5 years (Rambler drinkware)
- Returns
- Free returns
Pros
- 5-year warranty
- Dishwasher safe, per YETI
- Free returns and free shipping for account holders
Cons
- One can size per model (16 oz and slim sold separately)
- No published cold-hold hours
- No lid option to use it as a tumbler
Best for 16 oz tallboys
3. BrüMate Hopsulator Trio
$29.99–$32.99
The Hopsulator Trio is BrüMate's 3-in-1: it holds a 16 oz can on its own, takes a freezable adapter for 12 oz cans, and ships with a BevLock lid that BrüMate says makes it a 100% leakproof tumbler, even with carbonated drinks. Push-Lock lets you swap cans without unscrewing the gasket, per the brand.
BrüMate claims up to 24 hours cold and up to 4 hours hot, both with the lid on. Gaskets, lids and adapters are top-rack dishwasher safe, and BrüMate says most Trio bodies are too.
Trios were $29.99 to $32.99 on BrüMate's site depending on the finish. One catch most buyers miss: BrüMate says storing the Trio body in the fridge or freezer can damage the insulation and voids the warranty, so only the adapter goes in the freezer. The site advertises a lifetime warranty and free US shipping on orders over $90. For slim cans, BrüMate sells a separate Hopsulator Slim.
- Fits
- 16 oz cans; 12 oz cans with included adapter
- Lid
- BevLock lid included (leakproof, per BrüMate)
- Cold / hot claim
- Up to 24 hours cold, 4 hours hot with lid (per BrüMate)
- Cleaning
- Top-rack dishwasher safe parts; most bodies too
- Warranty
- Lifetime (freezer storage voids it)
- Shipping
- Free on US orders over $90
Pros
- Handles 16 oz and 12 oz cans plus works as a sealed tumbler
- Longest cold claim among the can coolers here, per the brand
- Lower price than Frost Buddy's solid colors
Cons
- Slim cans need a different model
- Putting the body in the freezer voids the warranty
- Free shipping needs a $90 order
Best big tumbler for all-day water
4. Stanley Quencher H2.0 FlowState Tumbler
$40–$55
The Quencher is a different tool: a big handled tumbler for water or iced drinks, not a can holder. The 40 oz version has a narrow base that Stanley says fits most car cup holders, a handle, a reusable straw and a FlowState lid that rotates between a straw opening, a drink opening and a full cover.
Stanley claims the 40 oz keeps drinks cold for 11 hours and iced for 2 days. It's dishwasher safe and weighs 1.18 lbs empty, per Stanley.
On Stanley's site the current holiday-collection Quencher was $40 (20 oz), $45 to $50 (30 oz) and $50 to $55 (40 oz) depending on the design; older colors sometimes appear lower in Stanley's last-call section. Free shipping starts at $50. Stanley doesn't describe the FlowState lid as leakproof, so keep it upright in a bag. Some editions are capped at 20 per order and excluded from promotions.
- Capacity
- 20, 30 or 40 oz
- Cold claim
- 40 oz: 11 hours cold, 2 days iced (per Stanley)
- Lid
- 3-position FlowState lid with straw
- Cleaning
- Dishwasher safe
- Weight
- 1.18 lbs (40 oz)
- Shipping
- Free over $50
Pros
- Holds a full 40 oz with a handle
- Fits most car cup holders, per Stanley
- Dishwasher safe
Cons
- Lid is not described as leakproof
- Some designs cost $5 more for the same size
- Not built to hold cans
Best sealed tumbler for coffee
5. Owala SmoothSip Slider
$29.99
If you want one cup for morning coffee and afternoon iced tea that can ride in a bag, the SmoothSip Slider is the simplest pick. Owala calls it leak-proof with a sliding lock, and describes it as triple-layer, vacuum-insulated stainless steel. Its product images claim 24 hours cold and 6 hours hot.
It comes in 12 oz and 20 oz sizes, with or without a handle, and with a stainless or ceramic interior. Owala says the lid, lock and gaskets are dishwasher safe but recommends hand washing the cup to protect the finish.
The product page showed $29.99 for the configuration we checked; other sizes or finishes may be priced differently. Owala lists 30-day returns and a limited lifetime warranty. It won't hold a can, so it complements rather than replaces a can cooler.
- Sizes
- 12 oz and 20 oz
- Lid
- Sliding lock, leak-proof (per Owala)
- Cold / hot claim
- 24 hours cold, 6 hours hot (per Owala's product images)
- Interior
- Stainless steel or ceramic
- Cleaning
- Lid parts dishwasher safe; hand wash cup
- Warranty
- Limited lifetime; 30-day returns
Pros
- Leak-proof sliding lock, per Owala
- Ceramic interior option for coffee drinkers
- Limited lifetime warranty
Cons
- Doesn't hold cans
- Cup body should be hand washed, per Owala
- Price can vary by size and finish
How we chose
We picked the can coolers and tumblers people compare most often, then made sure each pick answers a different need: every can size, standard cans only, 16 oz tallboys, big water tumblers and sealed coffee cups. Every price, claim and policy comes from the brand's own site, checked on Oct 27, 2026.
We compared:
- Fit: which can and bottle sizes each one takes without a separate model.
- Lid options: whether it can become a sealed tumbler.
- Cold-hold claims, labeled as the brand's own numbers.
- Cleaning rules, because dishwasher limits are where finishes and warranties get lost.
- Warranty, returns and free-shipping thresholds.
We did not test these products. Frost Buddy is our top pick and has a full Search Wary review; we may earn a commission if you buy through our link. RTIC was considered, but its site blocked our checks, so we couldn't verify a current price.
What to look for
Start with what you actually drink
If your fridge has standard cans, slim seltzers and the odd 16 oz tallboy, one universal sleeve saves you from buying three. If you only drink standard 12 oz cans, a single-size cooler like YETI's is simpler. If you mostly drink water or coffee, skip can coolers entirely and buy a tumbler.
Read cold-hold numbers as marketing, not lab results
Brands rarely publish their test conditions. A claim made with a lid on, ice in the cup or a pre-chilled drink won't match a sunny tailgate. Use the numbers to compare a brand against itself, not across brands. A 24-hour claim with the lid on tells you little about an open can.
Check the cleaning rules
YETI, BrüMate (most bodies) and Stanley say their products are dishwasher safe. Frost Buddy and Owala recommend hand washing the body. BrüMate also warns that keeping the Trio body in the freezer voids the warranty.
Quick comparison
| Pick | Price | Holds cans | Sealed lid |
|---|---|---|---|
| Frost Buddy Universal Buddy | $39.99 | 12 oz, slim, 16 oz | Optional coffee lid |
| YETI 12 oz Colster | $30 | 12 oz only | No |
| BrüMate Hopsulator Trio | $29.99–$32.99 | 16 oz, 12 oz with adapter | Included |
| Stanley Quencher H2.0 | $40–$55 | No | Not called leakproof |
| Owala SmoothSip Slider | $29.99 | No | Yes |
Watch the shipping threshold
Free shipping starts at $50 (Stanley), $70 (Frost Buddy) and $90 (BrüMate), and YETI ships free to account holders. A single can cooler under those thresholds can cost several dollars more than the sticker price.
FAQ
What's the difference between a can cooler and a tumbler?
A can cooler is an insulated sleeve that holds a sealed can or bottle. A tumbler is a cup you pour a drink into, usually with a lid. Hybrids like Frost Buddy's Universal Buddy and BrüMate's Hopsulator Trio do both: they hold cans, and an added lid turns them into a tumbler.
Does the Frost Buddy fit slim cans?
Yes, per Frost Buddy. The brand says the Universal Buddy fits 12 oz slim cans, 12 oz standard cans, 12 oz bottles and 16 oz cans and bottles in one sleeve. That's the main reason it's our top pick; YETI and BrüMate sell separate slim-can models.
Which can cooler keeps drinks cold the longest?
Among brand claims, BrüMate says the Hopsulator Trio keeps drinks cold up to 24 hours with its lid on, and Frost Buddy claims 12+ hours. YETI doesn't publish a figure. These are each brand's own numbers under its own conditions, so treat them as rough guides rather than a fair head-to-head.
Are insulated can coolers dishwasher safe?
It varies. YETI says the Colster is dishwasher safe, and BrüMate says Trio parts and most bodies are top-rack safe. Frost Buddy recommends hand washing the Universal Buddy. Stanley lists the Quencher as dishwasher safe, while Owala says to hand wash the SmoothSip cup and put only the lid parts in the dishwasher.
Is a YETI Colster worth $30?
If you only drink standard 12 oz cans and value a 5-year warranty, free returns and dishwasher-safe cleaning, it's a fair price. If you also drink slim cans or 16 oz tallboys, a multi-size cooler like Frost Buddy or BrüMate covers more for a similar price.
Can I put a Stanley Quencher in a bag?
Stanley describes the FlowState lid as having a full-cover position, but it doesn't call the lid leakproof. If you need a cup that can lie sideways in a bag, a tumbler sold as leak-proof, like the Owala SmoothSip Slider or a BrüMate Trio with its BevLock lid, is a safer bet.
