John Doe XTM-Air Armor for Elbow/Knee/Shoulder "A" Type - Standard Issue ready Alpinestars’ crash detection triggering algorithmThis "A" Type shape is the same size as Level 1, but measures 9. 5mm thick instead of the standard Level 1, which is 6. 5mm thick. Note: We now also have John Doe Type B Knee Armor, which ups the coverage from the standard approx. 7. 5x4. 5 inches to a full 9x6 profile. Because of the John Doe armor positioning system, it's easy to get away with less, because the rider can position the armor with pinpoint accuracy to help cover the crucial kneecap.
