Super Tough Case DURO: A New Era of Impact Protection

The newly developed Super Tough Case DURO represents a significant advancement in the DURO series. It features a novel structure that integrates rigid aramid fiber with flexible TPU. While aramid fiber provides exceptional strength, its rigidity previously limited coverage in areas prone to impact, such as the sides and corners. The addition of TPU addresses this challenge, enhancing impact resistance while maintaining the DURO series’ characteristic slimness and premium feel.

This hybrid integration of distinct materials—hard aramid fiber (Kevlar® 600D from Arclin, USA) and soft TPU—allows each material to perform its optimal role. The aramid fiber provides rigidity to the back surface, while the TPU offers cushioning and secure grip for the sides and corners.

Key features of the Super Tough Case DURO include:

  • Hybrid Integrated Molding: Combines aramid fiber and TPU for balanced rigidity and shock absorption.

  • MIL-STD-810H Compliance: Offers robust impact protection.

  • Slim and Lightweight: Approximately 1.3mm thick and weighing about 25g for iPhone 18 Pro (30g for iPhone 18 Pro Max), with only a 4-5g difference from the ultra-slim model.

  • Easy Attachment/Removal: The flexibility of TPU simplifies installation and removal compared to aramid-only cases.

  • Materials: Aramid fiber, TPU, aluminum, neodymium magnets.

  • Color: Matte Black.

  • Eye Comfort: The UV Cut / Blue Light Cut type of PREMIUM GLASS is suitable for outdoor use or extended screen viewing.

Usage Scenarios

  • On-the-Go and Outdoor Use: The Super Tough Case DURO is ideal for outdoor work, travel, or busy commutes, offering robust protection without sacrificing slimness and lightness. It can be easily attached to MagSafe car mounts.

  • Business Settings: The Ultra Slim & Light Case DURO Special Edition, with its refined aramid fiber texture and aluminum accents, fits neatly into suit pockets or slim bags. Paired with a MagSafe card case, it supports a minimalist, wallet-free lifestyle.
