Our cord is some of the best cord on the market. Made by the top braiders in the industry with high quality raw materials. Our 550, 450 and 425 tactical cords are all 100% nylon made from 840 denier nylon strands. This is some of the highest strength strands available in any paracord. It's as close to Mil-Spec as you can get without buying certified MIL-C-5040H cords.
