Iced coffee asks different things of a cup than hot coffee does. It needs room for ice, a lid that takes a straw or a spout you can sip while driving, and walls that do not drip onto your desk by mid-morning.
This guide compares eight cups made for the job, in insulated steel, plain glass, insulated glass and plastic. It says what each listing claims, what an outside reviewer found where we could read one, and which cup to skip for your routine.

Quick verdict: which iced coffee tumbler to buy
For most people, the best iced coffee tumbler is the Simple Modern Classic 28 oz: insulated steel with both a straw lid and a flip lid, and enough room for real ice. Want a small cup that closes? Choose the Owala SmoothSip 12 oz. Prefer glass at home? Choose the Simple Modern Glass 20 oz, or the REDUCE Aspen if you want glass with insulation.

Our picks for the best iced coffee tumbler
These eight cover the choices that matter: steel or glass, straw or spout, and small or large. Each pick says who it suits and gives one honest reason to skip it. Cold figures are the makers’ own, and we say where a listing gives none.
1. Simple Modern Classic 28 oz Tumbler – Two Lids, Plenty of Room for Ice
The pick for a daily iced coffee that has to last the morning. It holds 28 ounces, which leaves room for a full glass of ice and still a real drink, and the body is 18/8 stainless with double-wall insulation.
The useful part is the pair of lids. The listing includes a straw lid and a flip lid. Treeline Review, which reported using the 24-ounce Classic daily and running insulation and ice-retention checks, found the flip lid leakproof and called the straw lid splash proof, not leakproof. It also said cold insulation “does not perform as well” with the straw lid in use. So sip through the straw at your desk, and swap to the flip lid before the cup goes in a bag.
The listing says leakproof for the set without separating the two lids, so we would go with Treeline’s more careful reading. Its review covers the 24-ounce size, not this 28. A 24-ounce Simple Modern is already on our cold tumbler guide; we list the 28 here because it is the size with room for ice, and the two-lid set is what suits a commuter.
Why we like it
- Comes with both a straw lid and a flip lid
- 18/8 stainless with double-wall insulation
- Cupholder friendly, per the listing
- Limited lifetime warranty, per the listing
Key specifications
| Model | CLSF-SF-28 |
|---|---|
| Capacity | 28 oz |
| Body | 18/8 stainless steel |
| Insulation | Double wall |
| Lid and straw | Straw lid and flip lid |
| Cold claim | Hot or cold “for hours”; no figure stated |
| Height | 9.3 inches |
| Care | Not stated on this listing |
Why we recommend it
It suits anyone who drinks a large iced coffee over several hours and wants one cup for the desk and the commute.
Skip it if you want a small cup. At 9.3 inches tall it is a lot of tumbler for a single cold brew, and the height may be awkward under a low brewer spout.
Pros and cons
Pros
- Large enough for plenty of ice
- A closing lid for travel
- Reviewer reports all-day cold on the 24-ounce size
Cons
- Straw lid is splash proof, not leakproof, per Treeline
- Care instructions are not on this listing
- Tall
2. Owala SmoothSip Slider 12 oz Tumbler – A Small Cup That Closes
Not everyone wants a straw. This 12-ounce Owala has a sliding spout instead, and the listing calls the lid completely leak-proof. Treeline Review’s author reported using this size nearly daily for more than 18 months and also found the slider lid leakproof, which is about the best independent support any cup here has.
There is a catch for iced coffee. Treeline recommends it mainly for hot drinks and says drinks “get cold quickly with slider unlocked”, which we read as the lid needing to stay shut to do its job. Owala rates it for cold up to 24 hours and hot for 6, with hand washing for the cup and a dishwasher-safe lid.
Twelve ounces is small once ice goes in, so treat this as a cup for a short pour or a strong cold brew. The 20-ounce size of this tumbler is on our main tumbler guide. We list the 12 here because it is the size the reviewer used, and a shorter cup fits under more spouts.
Why we like it
- Slide-top spout that closes, no straw to wash
- Cold up to 24 hours, per Owala
- Long-term use reported by Treeline Review
- BPA and phthalate free, per the listing
Key specifications
| Model | C07462 |
|---|---|
| Capacity | 12 oz |
| Body | Stainless steel |
| Insulation | Double wall |
| Lid and straw | Sliding spout, no straw |
| Cold claim | Up to 24 hours |
| Height | Listed as 3.25 inches here; a sibling color lists 5.8 |
| Care | Hand wash cup; dishwasher-safe lid |
Why we recommend it
It suits people who toss a cup in a bag, drink a modest amount and also want it for hot coffee on cold mornings.
Skip it if you are set on a straw, or you drink a large iced coffee. A reviewer also found drinks warm faster with the slider open.
Pros and cons
Pros
- Lid closes fully
- Works for hot and iced
- Limited lifetime warranty, per the listing
Cons
- Small once filled with ice
- Cup is hand wash only
- Height field on the listing looks wrong
3. Simple Modern Glass Iced Coffee Cup 20 oz – See-Through, With a Silicone Sleeve
Glass has one plain advantage over steel: you can see the drink, and only glass touches it. This 20-ounce cup is built for iced coffee, with a thick straw and a clear Tritan lid that quarter-turns onto threads inside the glass.
A silicone sleeve wraps the glass and a silicone base softens set-downs. Every part is dishwasher safe, which is unusually simple care for a cup with a straw. The listing says it fits most car cupholders.
It is single-walled, so do not expect insulation. Ice will melt at the normal rate and the outside of the glass can bead with condensation, though the sleeve takes care of most of the grip problem. It is still glass, and a hard drop is a real risk, sleeve or no sleeve.
Why we like it
- Designed for iced coffee and cold brew
- Threaded Tritan lid and a thick straw
- All parts dishwasher safe
- Silicone sleeve and base
Key specifications
| Model | ICL-S-20-ALBM-M |
|---|---|
| Capacity | 20 oz |
| Body | Glass with silicone sleeve |
| Insulation | None, single wall |
| Lid and straw | Tritan lid, straw |
| Cold claim | None stated |
| Height | 7.62 inches |
| Care | Dishwasher safe, all parts |
Why we recommend it
It suits someone who makes iced coffee at home and drinks it within the hour, and who likes to see the layers.
Skip it if the cup rides around all day or you want the ice to last. It is uninsulated and breakable.
Pros and cons
Pros
- Easy dishwasher care
- Threaded lid, not a push fit
- No metal or lined interior to think about
Cons
- No insulation
- Glass can break
- No leak claim beyond a secure fit
4. Ello Ava 18 oz Glass Tumbler – A Fluted Glass With a Grip Band
The Ava is a smaller, prettier take on the glass iced coffee cup. Ribbed glass and a silicone band give it a grip and a pop of color, the straw is reusable, and the lid is described as splash resistant. Ello lists iced coffee first among its uses.
Eighteen ounces suits a normal homemade pour with a handful of ice. All parts are top-rack dishwasher safe and BPA free, and the listing says it fits most standard car cupholders.
As with any plain glass cup, it has no insulation, and splash resistant is not leakproof. Stand it up in the car; don’t lay it in a tote. Ello also sells a 24-ounce Ava if you want more room for ice.
Why we like it
- Top-rack dishwasher safe, all parts
- Silicone grip band on ribbed glass
- Reusable straw included
- Fits most standard cupholders, per the listing
Key specifications
| Model | 873-1899-004-8A |
|---|---|
| Capacity | 18 oz |
| Body | Ribbed glass with silicone band |
| Insulation | None stated |
| Lid and straw | Splash-resistant lid, reusable straw |
| Cold claim | None stated |
| Height | 8.89 inches |
| Care | Top-rack dishwasher safe |
Why we recommend it
It suits someone who wants a good-looking cup for the kitchen and the short drive, or a small gift for a coffee drinker.
Skip it if you need the drink to stay cold for hours, or the cup will ride on its side in a bag.
Pros and cons
Pros
- Pleasant shape and grip
- Simple cleaning
- Sold in a larger size too
Cons
- No insulation
- Splash resistant only
- Glass can break
5. REDUCE Aspen 20 oz Insulated Glass Tumbler – Glass Inside, Insulation Around It
If you like a glass cup but hate warm iced coffee, this is the compromise. A borosilicate glass cup sits inside a vacuum-insulated sleeve, and REDUCE says it keeps drinks cold for up to 12 hours. The lid and straw fit both the glass and the sleeve.
The straw is extra wide, sold for boba and thick smoothies, which also suits a blended coffee. REDUCE’s Soft Sit base is meant to quiet set-downs, and the listing calls the cup dishwasher safe and cupholder friendly.
It is a tall cup, listed at 10 inches, so check your cupholder and your cabinet shelf. We did not find an independent review of this model in the search we ran, so everything here comes from the listing. Twelve hours is the maker’s figure and the only one we have.
Why we like it
- Borosilicate glass with a vacuum-insulated sleeve
- Cold up to 12 hours, per REDUCE
- Extra-wide straw for thick drinks
- Lid fits both the glass and the sleeve
Key specifications
| Model | Aspen; number not stated |
|---|---|
| Capacity | 20 oz |
| Body | Borosilicate glass with vacuum-insulated sleeve |
| Insulation | Vacuum sleeve |
| Lid and straw | Lid with extra-wide straw |
| Cold claim | Up to 12 hours |
| Height | 10 inches |
| Care | Dishwasher safe |
Why we recommend it
It suits someone who wants the feel of glass and also wants the ice to survive the morning.
Skip it if you want something light and simple. Two main pieces mean more to wash, and glass can still break.
Pros and cons
Pros
- Glass drinking surface with insulation
- Wide straw takes thick drinks
- Quiet base
Cons
- Tall
- Rests on the listing alone
- Straw lid, so don’t lay it down
6. Keurig Iced Tumbler 16 oz – Brews Straight Over the Ice
This one solves a small, specific problem. Keurig says it fits under all Keurig brewers, so you can fill it with ice and brew straight into it. A tall tumbler often will not clear the spout, and this one is 6.2 inches high without its straw and 9.4 with it.
It is a double-walled, BPA-free plastic cup that holds 16 ounces and goes on the top rack of the dishwasher. Plastic will not keep a drink cold as long as vacuum steel, but the cup is light.
Remember that hot coffee over ice dilutes as it melts, so use a stronger brew setting if your machine has one and pack in more ice than seems sensible. The listing is short and gives no cold figure or warranty.
Why we like it
- Fits under all Keurig brewers, per Keurig
- Double-walled plastic, BPA free
- Top-rack dishwasher safe
- Straw included
Key specifications
| Model | 5000374474 |
|---|---|
| Capacity | 16 oz |
| Body | BPA-free plastic |
| Insulation | Double wall |
| Lid and straw | Lid and straw |
| Cold claim | None stated |
| Height | 6.2 inches, 9.4 with straw |
| Care | Top-rack dishwasher safe |
Why we recommend it
It suits Keurig owners who want iced coffee at home with no second container and no struggle getting a cup under the spout.
Skip it if you want hours of cold. There is no vacuum insulation, and it holds less than most cups here.
Pros and cons
Pros
- Sized for the job
- Light and easy to wash
- Short enough for a brewer
Cons
- No cold claim
- Plastic, not steel or glass
- Sparse listing
7. HydroJug Everyday Tumbler 20 oz – A Ceramic-Lined Steel Cup
Some people find coffee picks up a metallic note from steel, and this tumbler is aimed at them. HydroJug says the ceramic-lined interior prevents flavor transfer and names coffee, matcha and cold brew. We have not seen an outside check of that claim, so read it as the maker’s wording.
The body is vacuum-insulated stainless steel with what the listing calls triple-wall insulation and no outside condensation. A flexible straw and soft-touch lid are described as spill resistant for upright use, and the listing notes a non-slip base and a fit for most standard cupholders.
The listing says “for hours” and gives no figure. It calls the tumbler dishwasher safe. Note the wording on the lid: spill resistant and designed for upright use, which is not the same as leakproof.
Why we like it
- Ceramic-lined interior, per HydroJug
- Triple-wall vacuum insulation, per the listing
- Flexible straw
- Dishwasher safe, per the listing
Key specifications
| Model | Everyday Tumbler |
|---|---|
| Capacity | 20 oz |
| Body | Stainless steel, ceramic-lined |
| Insulation | Triple-wall vacuum |
| Lid and straw | Soft-touch lid, flexible straw |
| Cold claim | “For hours”; no figure stated |
| Height | 7.64 inches |
| Care | Dishwasher safe |
Why we recommend it
It suits someone who likes the toughness of a steel cup but wants a lined interior for coffee.
Skip it if you want an independent cold result to lean on. We have only the listing here.
Pros and cons
Pros
- Lined interior for flavor-sensitive drinkers
- Goes in the dishwasher, per the listing
- Medium size suits most pours
Cons
- Maker’s taste claim, not independently checked
- No cold figure
- Upright use only
8. Kensal Home 24 oz Reusable Iced Coffee Cup – Light Plastic, Venti Sized
This is the coffee-shop cup in reusable form: a double-wall plastic cup with a snap-tight twist lid. The listing says 24 ounces holds a Venti, and it comes with a plastic straw, a stainless straw and a slim cleaning brush.
Plastic is the reason to pick it, since the listing describes the cup as shatter resistant. The maker calls the lid leak resistant when upright and says the cup stays dry on the outside. It is a small Amazon-first brand, so there is little to go on beyond the listing.
Care is the drawback. The listing says hand wash only, with the brush included for the straws and the bottom of the cup. A 16-ounce size is also sold.
Why we like it
- Double-wall plastic, BPA free
- Two straws and a cleaning brush
- Shatter resistant, per the listing
- Holds a Venti, per the listing
Key specifications
| Model | KH-24oz-black |
|---|---|
| Capacity | 24 oz |
| Body | BPA-free plastic |
| Insulation | Double wall |
| Lid and straw | Twist lid; plastic and steel straws |
| Cold claim | “Colder longer than a standard plastic cup”; no figure |
| Height | Not clearly stated |
| Care | Hand wash only |
Why we recommend it
It suits someone who wants a big cup that survives a drop, for a homemade iced coffee on the school run or a walk.
Skip it if you want the dishwasher to do the work, or hours of cold. Choose steel for that.
Pros and cons
Pros
- Hard to break, per the listing
- Brush and spare straw included
- Large capacity
Cons
- Hand wash only
- No cold figure
- Thin brand, listing-only evidence
How to choose a cup for iced coffee
Tumbler listings all promise cold drinks. These are the differences a daily iced coffee drinker will notice.
Capacity, minus the ice
Ice takes up a large share of a cup, so a 12-ounce tumbler holds a short drink once packed. If you buy large coffee-shop drinks, 20 to 28 ounces is the range to look at. If you brew strong at home and drink it quickly, 16 to 18 ounces is plenty.
Straw, slider or flip lid
A straw is easy while driving and at a desk, but the opening means a straw lid is rarely leakproof, and Treeline Review found that on the Simple Modern Classic. A sliding spout closes properly but means tipping the cup. If the cup travels in a bag, buy one with a closing lid.
Steel, glass or plastic
Vacuum steel is the safer bet for hours of cold and survives drops. Glass shows the drink and is simple to clean, but plain glass does not insulate and it can break. Double-wall plastic is light and hard to break, though no listing here gives it a cold figure. Insulated glass and lined steel are for people who care about the drinking surface and accept more parts or a maker’s claim they can’t check.
Height against your brewer and cupholder
If you brew straight into the cup, measure the gap under your spout. Most of these cups are 7.5 inches or taller, and some listings are unreliable on height, so check the photos too. Listings say most cupholders; few promise all.
How you will wash the straw
A straw that goes on the top rack of the dishwasher is a straw that actually gets clean. Milky iced coffee leaves a film, so check the care line before you buy, and keep a straw brush near the sink for any cup you use daily.
How we picked these eight iced coffee cups
We started with cups that the maker sells for iced coffee or cold brew, kept only what was in plain stock with a new offer, and left out colorways of the same cup. We read the Amazon listing for each and took specifications from there. We have not used these cups ourselves, so nothing here is a personal result.
For outside evidence we read Treeline Review’s insulated tumbler review, which covers the 24-ounce Simple Modern Classic and the 12-ounce Owala SmoothSip, though it reports on cold drinks in general and does not discuss iced coffee by name. Our search otherwise turned up affiliate roundups we chose not to use, and one larger roundup that would not open. So the other six picks rest on their listings.
We kept this page apart from our cold tumbler guide, which covers large straw cups for water and all-day drinks. Two cups here share a line with cups on our other pages, at a different size, and each write-up says why.
Iced coffee tumbler questions, answered
Can I brew hot coffee straight into one of these?
Check the listing first. Keurig’s cup is made to go under its brewers. Glass listings here describe cold drinks, and a chilled glass can crack under a very hot pour, so brew over plenty of ice or let the coffee cool a little first.
Does a straw make iced coffee warm up faster?
It can. Treeline Review found the Simple Modern’s cold insulation “does not perform as well” with the straw lid. The difference matters most if the cup sits for hours.
Why does my cup drip on the outside?
Condensation forms when a cold wall meets warm air. Vacuum and double-wall cups keep the outer wall nearer room temperature, while plain glass gets wet. A silicone sleeve helps with grip, but the moisture is still there.
How do I get coffee smell out of a straw lid?
Take the gasket and straw apart if they come out, wash them right after use, and use a straw brush. Follow the maker’s care line, since some lids are dishwasher safe and some cups are not.
Is a bigger cup always better?
No. A 28-ounce cup is tall and heavy when full. If you drink a single cold brew in an hour, a 16- to 20-ounce cup is easier to live with and fits more spouts and shelves.
Our last word on iced coffee cups
Buy the Simple Modern Classic 28 oz if the cup goes everywhere with you, and the Owala 12 oz if you want a lid that closes and a shorter pour. At home, glass is the nicer way to drink it.
