AULUMU A18 Ultra-Slim Gradient Aramid Fiber Case for iPhone 18 Pro Max (2026)

An ultra-slim full-cover aramid fiber case with a woven grayscale gradient. A18 combines lightweight protection, CoolHyper heat dissipation, an aluminum alloy camera guard, thermochromic temperature indication, and strong magnetic compatibility in a 1.2mm profile.

•        Gradient-Woven Aramid Fiber — a woven grayscale gradient creates layered texture without relying on a printed surface pattern.

•        Full-Cover Protection — wraps around the sides, corners, and buttons for more complete everyday protection and a seamless profile.

•        1.2mm Slim & 26g Lightweight — engineered to preserve the slim, lightweight feel of your iPhone with minimal added bulk.

•        Upgraded CoolHyper Cooling — a silicone thermal pad, aluminum heat sink, and honeycomb ventilation structure help transfer and release heat more efficiently.

•        Aluminum Camera Guard — hard-anodized aluminum alloy protection helps reduce scratches and everyday wear around the camera area.

•        Strong MagSafe Compatibility — built-in magnets provide stable alignment with compatible chargers, stands, power banks, wallets, and other magnetic accessories.
