DURO® Super Tough Case
Most of this case is aramid fiber. TPU only shows up where the case actually needs to flex — around the edges and corners — so the case can pass MIL-STD-810H drop testing without turning into a brick. It's built as one piece, not fiber glued over a shell.
1.3mm Thin x Military-Grade Tough
Full military-grade coverage usually comes with a case that feels like a brick in your pocket. This one sits at about 1.3mm and 25g for the Pro, 30g for the Pro Max. The buttons don't even get cutouts — they're wrapped in aluminum so presses stay sharp instead of mushy.
Genuine Kevlar® fiber
The case is 600D Arclin™ Kevlar® aramid fiber, the same material used in body armor, doing almost all of the protective work itself instead of relying on a thick layer of plastic. TPU is only added where the fiber alone can't take the stress — which is how the case stays this thin and still passes MIL-STD-810H.
Dust-Proof Aluminum Protection
The camera ring is wrapped in aluminum alloy, not bare plastic, so it holds its shape after the case has been dropped a few times. Same story with the side buttons — aluminum-covered rather than cut open, which keeps dust and grit from working their way in over time.
MagSafe x Wireless charging
There's a ring of neodymium magnets molded into the case itself, so chargers and mounts click into place the way they would on a bare iPhone. Wireless charging passes straight through too — nothing to flip open or peel back first.
【 MIL-STD-810H Certified 】
MIL-STD-810H is the U.S. military's standard for testing gear against real drops, vibration, and shock — it's not a marketing number.
Super Tough Case is certified against it, so the drop protection here is backed by an actual test, not just how solid the case feels in your hand.
