Frosted finish

A phone case spends its life in your hand. It shouldn’t look like it. Because looking good on day one is one thing. Staying that way is another.

A phone case spends its life in your hand. It shouldn’t look like it. Because looking good on day one is one thing. Staying that way is another.

the best of both

Dual material design.

Protection isn’t just about adding more material. It’s about using the right material in the right place.

Synthesis pairs a rigid polycarbonate back with a ShockLite™ perimeter, combining structural rigidity with impact absorption where it matters most. The result is exceptional drop protection, tested to 4.6 m / 15 ft, without unnecessary bulk.

Don't just take our word for it.

Great, slim case

"I have dropped my phone a couple of times with other cases that I have purchased to be impact resistant, but my phone has been broken in all of them. This was the only case that properly protected my phone from a drop, and the case had no damage to it either."

Still have questions?
Our FAQs can help.

Yes. iPhone 18 series and iPhone 17 series cases are cross-compatible, but there are minor differences in fit between the two generations. 

Because the iPhone 17 and iPhone 18 series differ slightly in dimensions, a case designed for one generation may not fit the other quite as precisely. For example, the camera plateau on the iPhone 18 series is a fraction of a millimeter taller than on the iPhone 17 series. Our iPhone 18 cases are designed around that change, while our iPhone 17 cases are not. The differences are minor, but depending on the case and model, you may notice a slight variation in fit.

In addition, swappable buttons should not be mixed between generations. Because the buttons and cases are manufactured to very tight tolerances, buttons designed for iPhone 17 series cases may not operate properly in iPhone 18 Pro and Pro Max cases, and vice versa. When purchasing additional buttons, please choose the version made for your specific case generation.

No, Synthesis is made from a rigid polycarbonate back and ShockLite™, our proprietary flexible polymer. Polycarbonate does not "yellow" the way clear TPU cases might.

Yellowing in clear cases usually comes down to the material itself. Standard TPU is soft and porous, and reacts with UV exposure and oils from everyday handling, which causes that telltale amber tint over time. Polycarbonate is a denser, more chemically stable material, so it resists that kind of UV degradation and holds its clarity far longer. We designed Synthesis with this in mind.

Synthesis is designed for outstanding grip without sacrificing comfort. Its distinctive dot matrix pattern features over 300 subtly raised, rounded micro-dots along the perimeter for added traction, while the lightly textured, frosted back shell further enhances grip. The result is a secure, comfortable feel in hand.

All three offer excellent protection, but each has a distinct feel and design.

Sheath pairs our signature pebbled texture with a slim, minimalist profile for a balanced combination of grip, comfort, and protection.

Synthesis has a more structured feel, with a rigid back shell and distinctive dot matrix pattern along the perimeter for added grip.

Paragon offers a more refined in-hand feel, with a matte finish, sculpted perimeter, and our Adaptive Edge screen lip, which rises at the top and bottom for protection while sitting nearly flush along the middle of the display for effortless swiping.

Gorgeous with classy buttons of my 18 Pro Glacier

Good form, fit, and function. It provides robust protection without a lot of extra bulk, is attractive, and the Precision fit is spot on and all the cutouts are in the right place; while the Open style would also look great, I didn't want to risk scratching up the camera plateau. The bottom is comfortable to rest my pinky as I'm holding the phone.

The Celestial Blue color complements the Glacier on the phone, and the frosted back looks great. The front lip of the case is tall enough for a screen protector and still retains a bit of clearance.

The camera button feels natural and works perfectly and is far preferable to the cutout the some other cases have. It's great that Caudabe offers color choices in buttons so that I can customize the case to my own preferences. The standard Blue buttons look good, but it's also easy to swap in Brick buttons for contrast and I also have a set of Sage buttons for a fresh look as well.

Synthesis in Iris

I absolutely love and recommend the SYNTHESIS case! It's gives an awesome grip to your iPhone which is important because You Won't Drop It!😂 Very attractive, minimalist case, in Iris, it has deep violet sides with matching purple buttons. The lips over screen and camera are perfect protection. The back is slightly translucent so you can enjoy the color of your device. I Love it!

One if not the best!

I recently purchased the Sheath and Paragon cases for my iPhone 17 Pro Max. Among the three, the Synthesis case stands out as my favorite. It offers the perfect balance of aesthetics, feel, and weight for my needs. The Synthesis case weighs 1.75 oz (49.6 g), making it lightweight yet sturdy.

In terms of heat dissipation, the case performs well. The back of the case has a matte finish with a subtle texture, providing a comfortable grip. It also works seamlessly with most screen protectors, including ESR, Flolab, and DBrand. The sides of the case offer excellent grip, ensuring that my phone stays securely in place.

I’m a frequent and loyal customer, having tried out several other brands of cases in my quest for the perfect one. Despite my extensive search, I’ve consistently returned to Caudabe for my iPhone cases.

Denis (United States)
One of the best cases for my phone.

The phone arrived with a very minor cosmetic defect. However, it feels great in the hand and offers good protection for the screen and camera; the case isn't slippery, yet it looks stylish and not bulky. The build quality is excellent, too—there are no gaps or loose parts.

Frost Synthesis

This case was exactly what I was looking for. I love using dbrand skins, but wanted a clear case that would display the skin while keeping fingerprints at bay. Not only does this case do exactly that, it also feels good in my hands. I don’t worry about losing my grip. I also added grey buttons for an additional touch. Love this case!

Keep making cases like this and you've got a customer for life, Caudabe!

I was always on "Team Clear Case" ever since I got my first iPhone 3G, but I decided to switch it up to the Synthesis after hearing nothing but great things and they were not exaggerating. This case adds more protection, but it doesn't feel too bulky or uncomfortable to hold. It also feels confident in my hand with the side grips and if I ever drop my phone, I'm not going to be worried in the slightest. I got the orange side buttons to go with my Cosmic Orange 17 Pro and it really adds that "pop" to it that I've had several friends comment on it. I will definitely be checking out Caudabe when I go to upgrade my phone in the future.

My first online product review - Mous to Torras to Caudabe.

If you’re on the fence about the Sheath or Synthesis, just buy it. I use phones until they fall apart so I spent ~a lot~ of time researching phone cases. I was a Mous guy until my iPhone13 Pro spiderwebbed due to falling out of my truck onto gravel. After extensive research my iPhone17 Pro Max, I ordered a Mous Limitless, Caudabe Sheath, and Torras Q3 Air. The Mous felt cheap in hand and they’d already fooled me once. The Torras had the looks and it felt good in my hand, but it was shelved when I read drop testing data.

The Sheath in Celestial Blue with the sand-colored buttons has been my daily beater. It proved itself after my first ski trip to Aspen where I crashed so hard (on multiple occasions) my Apple Watch offered to call 911 but the phone was spotless even though it was in a loose pocket. I like the Sheath for full coverage its full coverage when I’m at the gym or traveling. It is easy to grip in gloves and somehow the grip improves when you’re sweaty. I also like the full coverage which offers more dirt and grime protection.

I like the Synthesis for daily use. The side grip is more aggressive than the Sheath, which I like, and the frosted, textured back panel feels good on your finger tips. The MagSafe magnets hold up to me trying to shake an ohsnap grip 5 off and they allow my phone to charge on Anker wireless chargers. I rock the Abyss Blue Sheath with silver buttons and an ember action button accent.

Caudabe, please make an iPhone 17 case in pink or purple so I can show my girlfriend the light, too. Also, if y’all can figure out how to make a Synthesis that has the camera plateau cover similar to a paragon, I’d be the first in line.

Keep making cases like this and you've got a customer for life, Caudabe!

I've been on "Team Clear Case" since the iPhone 3G, but after doing a lot of research for a case for my 17 Pro, the Synthesis was mentioned in several videos and reviews and after having it for a month, I see why. I don't like bulky cases, but this case is a great balance between bulk and protection. Super comfortable to hold, confident in my hands with the side grips and the USB-C port doesn't destroy my pinkie when I'm holding the phone with one hand. I sprung the extra cash for the orange side buttons and it really accents my Cosmic Orange. I've had multiple people ask where I got it from. 10/10, you knocked it out of the park.

Perfect! My favorite clear case.

I have the silver iPhone 17 Pro Max. This is exactly what I was looking for. The case fits snug on the phone. The rubber feels like great quality material with bumps that give it a nice grip. It’s clear with a textured back that doesn’t leave a greasy feel like most clear cases do. That’s a big one for me. I hate having a clear case that gets greasy from your fingers. It doesn’t feel bulky and it has a nice lip around the front glass and back plateau. This is a great case if you want to show off the color of your phone. I’m impressed and will be keeping this one on.

Best Case Scenario

The Synthesis is a beautifully crafted home for my new iPhone 17 Pro. The buttons are clicky and secure, the side grips are addictive to hold and the overall fit is perfection. While not a slim case per se, the Synth is very pocketable and is an ideal combination of minimal and protective. It’s really as great as so many people are saying.

Wow, this is the best case I’ve ever used!

The Caudabe Synthesis case for the iPhone 17 Pro Max is the best case I’ve ever used. The grip is excellent, the frosted back looks great, and the MagSafe magnets are exceptionally strong. The ember-colored buttons were very easy to install and add a nice accent. The case also provides sufficient lip raise along the sides to protect the screen when the phone is laid flat.

Love the Synthesis Frost for my 17 Pro Max. It is the best case I have ever had! The case is really high quality, and you feel it since minute one. The grip is excellent, and the feel in hand is perfect. I buy an Ember buttons pack and I love how it looks in my Blue 17PM. Absolutely recommend this case.

The perfect case

Order this case right now. The reviews don’t lie. I never leave reviews on anything but I feel the need to with this case, there’s no other case that I’ve ever had that compares to this case, everything about it is perfect. It feels amazing in the hand too, just a very high quality case. Not a single complaint or thing that I would change about this case.
