Perforated for hotter weather, Apex pants allow more air to reach legs without sacrificing safety. On front panels, perforations are there for cooling and places where abrasion is possible, solid panels are sewn in with six ply bonded nylon stitching. Track day riders will appreciate extra cooling while out blasting laps. CE armor for hips and knees protect vital areas. Large Velcro patches allow rider to put on knee pucks to gauge lean angles. Pre-bent knee armor moves with accordion stretch panels to increase range of motion without binding. Zip in Apex perforated leather pants to your favorite Tour Master jacket for a complete two-piece suit.
