My new favorite brand

Brilliant case, perfect mix of rugged and sleek!
"Used to use Otterbox but this is now the one for me. Ideal mix of protection and slim, easy to use. Buttons are excellent too. Highly recommend!"

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."

Probably the best case out there
"It is very strong, but still minimalist. It is also very comfortable in your hands, having a great fit, and the material is smooth but not slippery. Honestly, I think it's probably the best case I've ever had for an iPhone."

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.
