At Undercover Jeans, we had to find the Kevlar and Keprotec that would be the strongest and that would therefore provide the best coverage. After extensive Taber Abrasion Testing, we selected the grade of Kevlar that provided the best coverage in the lab. Next, we needed to make sure our Kevlar would provide great coverage in a more practical setting - on the road. Our Keprotec consists of a blend of this Kevlar and nylon, to allow for a stretch jean that is even stronger than regular Kevlar.
