The Alpinestars Paragon Knee Guard is mainly constructed from a breathable stretch-mesh, so the fit is light and tight. Flexible high-density foam pads, similar to D30, are pre-shaped, ergonomically designed, and perforated for breathability — you might even forget they're there! They're built to slide on easy, and then stay put thanks to the elasticated cuffs and grippy silicone printing.
Though these guards are light on weight, they're not light on protection. Boasting CE certification, these perforated pads are tough enough to save your knees from any scrape, crash, or tumble that might befall you on your next adventure.
