OverviewFrom misty mountain mornings to days on the river, Decoy is ready for it all. Featuring an 8-base frame with ProFlex Rubber and our Auto Sun lens, Decoy goes all day without skipping a beat. Auto Sun is designed for days outside in changing light conditions. Photochromic technology automatically adjusts from a low-light, bright yellow with a 28% Visual Light Transmission (VLT), to a high visibility persimmon with a 15% VLT for sunny conditions, while polarization protects and heightens color, definition, and detail. Zeal Optics frames are made from Z-Resin, a unique plant-based polymer derived from the castor plant. This durable plant-based material contributes to a lighter weight frame, for more comfortable everyday wear and activities.
