Perfect Fit liner is meticulously crafted to match the contours of AGV K1 and K1S full-face helmets, delivering seamless integration without compromising comfort. Engineered with breathable, sweat-wicking fabric, it actively regulates temperature - absorbing moisture to keep you cool in summer while providing lightweight insulation for winter rides. Its secure inner lining reduces helmet slippage, ensuring stability even during aggressive riding or high-speed maneuvers. Designed for convenience, the liner is removable and machine-washable (gentle cycle recommended), making maintenance effortless for long-term freshness.
