KAPVOE Photochromic Magnetic Replacement Lens S1-S4 for K721 Ski Goggles

• 【Clear to Silver Photochromic S1-S4, VLT 4%-55% Replacement】 Starts clear, develops a silver tint as UV rises and becomes clearer as light falls. It keeps the same day-to-night S1-S4 use as the original K721 photochromic lens.
• 【Dual-Lens Anti-Fog Construction】 A hydrophilic anti-fog inner layer helps manage moisture while the dual-lens structure helps reduce condensation during changing temperatures and active descents.
• 【16-Point Magnetic Fit with Clip】 Connects to K721 ski goggles through a 16-point magnetic interface with clip support for a secure fit and fast swaps. Lens only; goggle frame not included.
• 【UV400 & Impact-Resistant PC】 The polycarbonate dual lens provides UV400 with 99.99% UVA/UVB filtering for daytime outdoor use and an impact-resistant construction for snowy, reflective environments.
• 【Replace Damage or Change Colour】 Use it as a direct replacement for a damaged K721 lens or switch to another verified photochromic colour while keeping the same day-to-night use.
