We offer three distinct models within our DURO® case lineup. While they share a similar aesthetic, each is engineered to meet specific user priorities. Every DURO® case is built on the same core foundation: a matte black case meticulously woven from genuine DuPont™ Kevlar® fiber.
We utilize genuine DuPont™ Kevlar® fiber because this advanced aramid fiber—widely trusted in body armor and aerospace engineering—delivers an exceptional strength-to-weight ratio roughly five times greater than steel. This material composition allows us to maintain an ultra-thin form factor without compromising structural protection.
Additionally, unlike carbon fiber, Kevlar® is inherently non-conductive. This ensures that your device maintains optimal cellular reception, GPS accuracy, and wireless charging efficiency across all three models.
DURO® — the original
Designed for those who prefer a naked-phone experience. Crafted from premium 1500D Kevlar®, it measures just 0.65mm thick (thinner than a credit card) and weighs a mere 11–15g (lighter than a AA battery). Featuring a matte, anti-slip finish with a subtle supercar-carbon texture, it ensures full wireless charging compatibility and zero signal interference.
-
Enhanced Grip: The specialized matte coating provides significantly better tactile grip than bare glass or aluminum, preventing drops before they happen.
-
Note: Supports standard wireless charging but does not include an internal magnet array. For MagSafe compatibility, we recommend the Special Edition.
DURO® Special Edition
The ideal balance of military-grade protection and ecosystem compatibility. Maintaining the high-grade Kevlar® DNA, this edition is slightly reinforced at 1.2mm thick and 19–23g. It features a reinforced camera guard, integrated MagSafe-compatible magnets, and official US military-grade drop certification (MIL-STD-810H).
-
Advanced Armor: The reinforced camera perimeter protects your device’s most vulnerable components from high-impact tumbles.
-
Low Profile: Delivers defense-grade confidence while remaining dramatically slimmer and lighter than traditional rugged cases.
DURO® Ring Master
Engineered for hands-free utility and secure, one-handed operation. This premium hybrid case combines Kevlar®, PC, and TPU with a flush-fitting, 360° rotating magnetic ring that serves as both an ergonomic grip and a multi-angle kickstand—complete with MagSafe compatibility and a MIL-STD-810H drop rating.
-
Versatile Utility: The ring rotates 360° to prop the phone in landscape for media, portrait for video calls, or fold completely flat when not in use.
-
Seamless Integration: Unlike bulky, stick-on accessories that peel off and block wireless charging, the Ring Master builds this functionality directly into the chassis for a sleek, uncompromised workflow.
The quick way to decide
- Want the lightest, most pocketable case? Original DURO®.
- Want the best protection-to-slimness ratio with MagSafe? DURO® Special Edition.
- Want a stand and grip built into the case itself? DURO® Ring Master.
Worth noting: the original DURO® charges wirelessly but doesn't carry MagSafe magnets, while the DURO® Special Edition and DURO® Ring Master both do. Whichever you choose, it's the same genuine DuPont Kevlar underneath, available across iPhone and other flagship phones.
