Aramid Fiber iPhone 18 Pro Max Case
The Mason Aramid Fiber Case is a 0.90 mm, 22 g MagSafe case for the iPhone 18 Pro Max, made from aerospace-grade 1500D aramid fiber with built-in magnets and a woven carbon fiber look.
For people who want the iPhone 18 Pro Max protected, not padded. Mason's case is made from aerospace-grade 1500D aramid fiber, with a carbon fiber look and finish that's woven in, not printed. It's 0.90 mm thick and weighs 22 g, so the phone still feels like the phone.
It's MagSafe ready, with magnets built into the case, so chargers, wallets and mounts snap on and hold. A raised lip runs around the full camera plateau, so the camera area doesn't touch the surface when the phone is lying on its back. Camera Control and the Action button stay open. Drop resistant without the bulk, and it won't stretch or yellow the way clear and silicone cases do.
Aramid fiber doesn't block cellular signal, while carbon fiber can, so you get the carbon fiber look without giving up reception.
Minimal branding, a matte texture that feels great in hand, and a build that holds its shape for years. If you're looking for a thin MagSafe case for the iPhone 18 Pro Max that respects the phone's design, this is it. See the rest of the iPhone 18 series cases, or the iPhone 18 Pro version.
