Workrite Uniform Co. developed a new Dickies FR denim jean line using Mount Vernon FR’s flame resistant (FR) fabric. The mid-weight denim collection features a 13-ounce FR fabric from Mount Vernon FR called Mustang Flex, combining the best in both protection and comfort. Mustang Flex is part of Mount Vernon FR’s extensive FR denim fabric collection, Phoenix FR.

“We always aim to provide consumers with garments that not only meet their needs for protection from hazards such as electric arc flash or flash fire, but also accommodate the comfort they want and deserve,” said Mark Saner, technical manager at Workrite Uniform Co. “Working with Mount Vernon FR has allowed us to create flame resistant clothing that offers the best of both worlds without tradeoffs in comfort, durability or protection.”

Mustang Flex denim adds mobility without reduction in FR protection, so workers experience increased comfort and range of motion when wearing the Dickies FR jeans. Mount Vernon FR’s Mustang Flex is engineered for increased comfort and movement, incorporating an elastomeric fiber that allows the fabric to elongate sideways and diagonally. This eliminates any sagging or bagging in the jeans, and makes reaching and bending easier for workers.

“We believe safety managers should never have to make compromises when it comes to the comfort and durability of the FR apparel that they provide to their employees,” said Mike Woods, vice president of FR fabrics for Mount Vernon FR. “Working with Dickies FR on this line of flame resistant jeans enables us to combine our shared dedication to innovation and customer satisfaction to create a collection that has durable FR protection, and looks and feels good.” 

The Dickies FR jeans are available in two washes, with a relaxed, contemporary fit.  The jeans meet the performance requirements of ASTM F1506, comply with NFPA 70E and are UL® certified to NFPA 2112.
