The Alpinestars Juggernaut WP motorcycle pants are CE-certified 89/686/EEC with Level 1 CE-certified height-adjustable Alpinestars Bio Armor protectors at the knees (hip protectors sold seperately). The multi-fabric shell construction with mesh panels on the thighs, lower legs and back gives an improved cooling performance with accordion zones above the knee for superior flexibility. Adjustability at the waist with a micrometric adjuster allows for a custom fit, and a zip allows attachment to Alpinestars jackets. Hook and loop strap on ankle closure prevents weather ingress, and a long zipped gusset running from the knees to the bottom legs enables easy fitting of the pants while wearing boots. An extended high rear waist construction prevents wind ingress for a comfier ride, along with a pre-curved leg construction.
