HJ-41 ShadeX Shield. The HJC HJ-41 ShadeX Shield adapts to light for clear vision without visor swaps. The HJC HJ-41 ShadeX Shield is built for riders who want consistent visibility without the hassle of changing visors. Designed specifically for the V10 helmet, this photochromatic shield automatically adjusts its tint as lighting conditions change, keeping your vision clear from bright sun to shaded roads and everything in between. It's a simple upgrade that lets you stay focused on the ride instead of your gear. ShadeX technology reacts to UV exposure, darkening quickly in bright environments and returning to a clearer state when light fades. With a visible light transmission range of 30 - 80% and 99% UV protection, it helps reduce glare and eye fatigue throughout the day. The Pinlock-ready design allows for added fog resistance, making this a reliable, all-in-one shield solution for changing conditions. Specs:
