Every X Caliber case is engineered for the people who care about how things are made. Just 0.8mm thin and 17g light, with a tactile aluminum camera bumper, machined metal side buttons, and full MagSafe compatibility. Drop-tested to 6.6ft so the slim profile never costs you protection.

From the all-black confidence of Blackout Carbon and Stealth Weave, to the bold contrast of Peak Divide, Race Day, and Prism Stripe, the collection is built around 20+ designs that range from quietly refined to unapologetically loud. Compatible with every iPhone from 12 through 17 Pro Max — including Plus and Pro Max sizes.

Whether you want a minimalist daily carry or a statement piece that catches the light, X Caliber cases hit the sweet spot between premium feel and design-forward style. Free shipping when you order 2 or more.
