5.11 Tactical makes purpose-built tactical apparel and uniforms for law enforcement, military, first responders, and prepared civilians, built on durability and functional design. The brand's origins trace to a climbing pant designed by Royal Robbins, named for the Yosemite Decimal System rating "5.11," which the FBI Academy adopted for its durability and pocket layout. That unexpected adoption led Dan Costa to found 5.11 Tactical in 2003, now headquartered in Irvine, California, focused on gear that holds up to hard professional use.

The lineup covers tactical shirts, pants, jackets and outerwear, and footwear, along with the accessories that round out a uniform. The original tactical pant remains a signature product, joined by no-fade polos and the ATAC boot line.

5.11's strength is apparel engineered for the job. Its garments use durable fabrics, reinforced stress points, and functional pocket layouts designed around the gear professionals carry, with combat shirts built to work under armor and low-profile designs that carry that function in civilian-appropriate styling. Stretch fabrics and articulated construction preserve mobility for climbing, kneeling, and hard movement, and moisture-wicking materials handle long shifts in heat. The through-line is clothing that performs as working equipment rather than ordinary wear, which is why 5.11 became a standard in duty and tactical wardrobes.
