The company name 5.11 is a reference to rock-climbing legend Royal Robbins, who with his wife, Liz, designed the original 5.11 pants in 1968. The number 5.11 signifies the most difficult level of rock climbing in the Yosemite Decimal System of rating climbs.

Originally designed as ultra-sturdy pants for mountain climbing, some Colorado-based FBI agents who were also climbers discovered 5.11 trousers were good for work and play.

Eventually, the pants ended up at the FBI training centre in Virginia. When top officers from around the world began wearing 5.11 products they got from the FBI, other officers wanted their own.  The 5.11 story now continues...
