The Smith-K features the same shell as the Smith but infuses a Para-Aramid liner in its interior for additional abrasion resistance and impact protection. The inner liner seamlessly integrates a triple layer on the seat of the pants for a single layer feel, while protecting against rough riding seat wear and tear. The Smith-K includes a built-in hammer loop and combines the comfort of stretch-blend fabric with the rugged intensity of heavyweight denim. Each pair comes with POWERTECTOR® CE approved hip and knee protectors, which are installed in easy to access knee pockets and secure internal hip pockets, complemented by our elastic accordion panels on the knees and lower back.
