The folks over at RAGGEDedge Gear use cutting edge fiber technology originally designed for aerospace, military, and industrial applications to bring us every day gear such as these wallets. If you didn’t already know, Kevlar and Technora are part of the Aramid family which is commonly used for body armor and flame resistant clothing. Yes we are talking about the same stuff they use to stop bullets and walk through fire. We don’t suggest you attempt to test this theory on the wallet, however it does make these wallets strong, water proof, lightweight and resistant to stains.
