Direct/public exposure to a pure 'Double Knee' brand is limited since Carhartt and similar names are privately held. The closest public plays are durable-workwear leaders such as VF Corporation (VFC) and Columbia Sportswear (COLM), which own brands that compete in rugged pants and reinforced-knee designs. Entrepreneurially, launching a niche double-knee line or knee-reinforcement accessories could capture margin in this durability-focused segment.
