5X Steel Strength: The advanced composite material (Aramid Fiber) we use to build the case is 5 times as strong as steel of the same weight. This material is commonly used in armor (bulletproof vest), spacecraft, jet engines and race cars. *Slim & Protective: While the case is only 1.6mm thin and lightweight, our Karbon case is also very protective. The case itself is military grade drop tested. It provides a good amount of protection without adding bulkiness. *Wireless Charging Compatibility: Due to the position of the metal inserts, the case will work with all wireless chargers. These inserts do not block the charging thus, will not take the charge energy away or heat up when wireless charging. Our case also will not interfere with WIFI, cellular, GPS, or Bluetooth signal. *Magnetic Vent Mount: There are metal inserts in the phone case, which will hold strongly to the magnetic vent mount that comes with the case. Our magnetic vent mount will turn your phone into a hands-free, transit-friendly tool.
