Additional: Velcro Hook for Attachment Material: Cordura 500D Due to its unique qualities, Cordura is widely used in tactical equipment for military, law enforcement, and special forces. It is mainly used in materials with a 1000d and 500d linear density. Linear density is the ratio between the weight of the fabric and its length. It is measured in denier. This unit of measurement is mainly used for nylon fabrics. So, the higher the index, the more dense and heavy the fabric. The physical and technical characteristics of CORDURA 1000D are very high, it has a very high breaking load of about 3000 N and a tearing load of about 150 N. The abrasion resistance is more than 50000 cycles. It is used for clothing, bags, and pouches. Products made of CORDURA will stand the test of time and distance. CORDURA stands for durability, reliability, and style. In terms of durability, it is beyond competition.
