Yes, there is an iPhone Duo case with a crossbody strap, and it is ready before the phone is
Short answer: Keebos makes a crossbody case for the iPhone Duo, Apple's first folding iPhone, and you can order it now. It is $49.90, it comes with a detachable 54-inch adjustable strap or a 45-inch chain, and it is assembled in Venice Beach, California. Like our Samsung Z Fold cases, the iPhone Duo case comes without the Keebos wallet, because the wallet does not fit a foldable. Free US shipping and a 30-day money-back guarantee.
If you searched for an iPhone 18 Fold case, an iPhone Ultra case or a folding iPhone case, you are in the right place. Those were the rumored names. Apple's official name is the iPhone Duo, and it is the same phone and the same case whichever name you found it under.
iPhone Duo release date, price, sizes and colors
Here is what Apple announced at its September 9, 2026 event, per Apple's newsroom, so you can plan the case around the phone:
- Preorder date: Friday, October 16, 2026
- Release date: Friday, October 23, 2026
- Price: from $1,999 for 256GB, with 512GB, 1TB and 2TB tiers above it
- Screens: a 7.6-inch inner display when open and a 5.4-inch outer display when closed
- Colors: star white and night sky
Two things follow from that list. First, this is a $2,000 phone, so the case question is not optional. Second, it has two states, closed and open, and a case has to work in both. That is exactly the problem a crossbody strap solves.
Why a folding iPhone is the phone that most needs a strap
A foldable is thick when it is closed and wide when it is open, and neither state belongs in a pocket. Closed, it is a dense block that pulls at your trousers and juts out when you sit down. Open, it is a two-handed device, so the moment you want to use it you have no hand left for a bag, a coffee or a set of keys.
Wearing it fixes both. The phone hangs at your side or across your chest instead of fighting your pocket, and when you open it up your hands are free because nothing else is in them. You also stop setting a $2,000 phone down on cafe tables, which is how folding phones get scratched, forgotten and stolen.
This is not new ground for us. Keebos has made a crossbody case for every Samsung Galaxy Z Fold since the Z Fold 3, so the iPhone Duo case follows a pattern we have been refining for years.
What you get in the Keebos iPhone Duo crossbody case
- A fitted case for the iPhone Duo. Cut for the folding body, with a 4-corner bumper to absorb shocks and a raised 3mm lip around the screen and camera. Most Keebos cases are clear, so star white stays white and night sky stays dark.
- Two connector rings built into the case. Every Keebos strap and chain clips onto them, so the strap comes off in seconds when you want a slim everyday case and goes back on when you head out.
- Your choice of strap or chain, included. Woven cord straps adjust up to 54 inches by pulling the ends. The Royal gold and onyx chains are 45 inches. Wear it crossbody or doubled up as a necklace.
- No wallet on this one. The sealable wallet on our iPhone 18 Pro and Pro Max cases does not fit a folding phone, so the iPhone Duo case ships without it. More on that below.
- The usual Keebos promises. Assembled in Venice Beach, California. Free US shipping. A 30-day money-back guarantee. One tree planted for every Keebos, and biodegradable packaging.
Pick the iPhone Duo from the phone model dropdown on any of these and it is the same $49.90:
- Sunset, clear case with a black cord and gold accents
- Voyage, clear case with a flat, adjustable black strap
- Royal Gold Chain and Royal Onyx Chain
- Pearl Paradise, clear case with a pearl strap
- Rialto, vegan leather strap with a gold chain, the pick if you searched for an iPhone Duo leather case

iPhone Duo case with strap: which strap for a folding phone?
Most iPhone Duo cases will be plain covers. Ours is built around the strap, and any Keebos strap works, so this comes down to how you will wear it. A few pointers from years of Z Fold customers:
- Wear it shorter. A foldable is heavier than a regular iPhone, and it rides best high on the chest rather than swinging at the hip. Pull the strap ends in a few inches and it stops being noticeable.
- The cord straps are the lightest option and come in nine colors at $22.90 if you want a second one to match an outfit.
- The chains dress it up. Gold on star white and onyx on night sky are the obvious pairings, but the clear case means either chain works with either phone color.
- Swap freely. Every strap clips to the same rings, so you can own one iPhone Duo case and several looks. Two straps are $29.90 together.

Looking for an iPhone Duo wallet case? Read this first
A lot of people search for an iPhone Duo wallet case, and we want to be straight about it: the Keebos wallet does not fit a foldable, so our iPhone Duo case has no card pocket. That is the same on our Samsung Z Fold 8 case. The strap, the chain, the bumper and the lip are all there; the wallet is the one thing a folding body cannot take.
If you already own a wallet case you like for the Duo, you do not have to give it up to go hands-free. The Keebos Universal Crossbody Strap at $34.90 attaches to any phone case, so you can keep the wallet you have and add the strap.
iPhone Duo vs Galaxy Z Fold 8: we make a crossbody case for both
If you are choosing between Apple's first foldable and Samsung's Galaxy Z Fold 8, the case is not a reason to pick one over the other. Keebos makes a fitted crossbody case for the Samsung Z Fold 8 as well, with the same straps and chains and the same $49.90 price, and the same no-wallet design for the folding body. Whichever foldable you buy, your straps carry over.
Will an iPhone 18 Pro Max case fit the iPhone Duo?
No. The iPhone Duo is a different shape from every other iPhone, so it needs its own case. Do not buy an iPhone 18 Pro Max case hoping it will stretch.
Your straps do carry over. Every Keebos strap and chain is detachable and interchangeable, so if you already own a Keebos for another phone, you only need the iPhone Duo case and can clip your existing strap onto it. If you own our universal strap, it attaches to any case you buy on day one.
Celebrities wearing Keebos
Keebos has been photographed on Eva Longoria, Scarlett Johansson, Tori Spelling and Gina Rodriguez, among others, on regular iPhones so far. The folding iPhone will be the first one worth keeping on a strap the moment it is unboxed. See everyone who has been spotted with a Keebos in our celebrity phone case post.
iPhone Duo Crossbody Case FAQ
Is there an iPhone Duo case with a strap?
Yes. The Keebos iPhone Duo crossbody case is $49.90 and includes a detachable strap or chain. Choose the iPhone Duo from the phone model dropdown on any Keebos crossbody case, or shop the iPhone 18 and iPhone Duo collection.
Is the iPhone 18 Fold case the same as the iPhone Duo case?
Yes. iPhone 18 Fold, iPhone Ultra and folding iPhone were the names used before Apple's September 9, 2026 event. The official name is iPhone Duo. It is one phone and one Keebos case.
Does the Keebos iPhone Duo case have a wallet?
No. The Keebos wallet does not fit a folding phone, so the iPhone Duo case comes without it, like our Samsung Z Fold 8 case. You still get the fitted case, the bumper and lip, the connector rings and the strap or chain.
When can I get an iPhone Duo case?
Now. The Keebos case is available to order today, and it ships from Venice Beach, California, so it can be waiting for you when the phone arrives. Apple's preorders open October 16, 2026 and the phone is available from October 23, 2026.
How much is the iPhone Duo, and how much is the case?
Apple lists the iPhone Duo from $1,999 for 256GB. The Keebos iPhone Duo crossbody case is $49.90 with the strap or chain included, and spare straps start at $22.90.
What size is the iPhone Duo?
Per Apple, it has a 7.6-inch inner display when open and a 5.4-inch outer display when closed. The Keebos case is cut for that folding body specifically, which is why a case for any other iPhone will not fit it.
Can I use my current Keebos strap on the iPhone Duo case?
Yes. Every Keebos strap and chain clips onto the same connector rings, so a strap from any other Keebos case carries over. You only need the new case.
Is there an iPhone Duo clear case?
Yes. Most Keebos cases are clear, so both iPhone Duo colors, star white and night sky, show through. The Voyage case is the exception if you prefer black.
Does Keebos make a case for the Galaxy Z Fold 8 too?
Yes. Keebos has made a crossbody case for every Galaxy Z Fold since the Z Fold 3, and the Z Fold 8 case is $49.90 with the same straps and chains.
What if I do not like it?
Every Keebos comes with a 30-day money-back guarantee. Email hello@keebos.com within 30 days of delivery and we will send return instructions for a full refund of the purchase price.
