The BLACK LABEL Mainline Pants provide a flawless fit with an undeniable style. A combination of rigid and stretch paneling work seamlessly to give you the perfect balance of durability and rider movement. The 600D polyester main body construction feels substantial, yet lightweight and shrugs off daily wear and tear. Articulation is utilized for more natural movements on the bike - thoughtfully cut and sewn, this strategic paneling puts you in the most comfortable riding position possible. On top of that, 4-way stretch knees and back yoke panels add flexibility in all the right places. For when temperatures rise, a combination of laser-cut perforations, vented knee panels, and breathable rear yoke work together to make sure you don't overheat mid-ride.
