We built our reputation on a high-quality performance product and we stand behind it. If you experience a manufacturing defect in materials or workmanship, Suncloud Optics warranties your sunglasses for the lifetime of the product and we will repair or replace the product at no charge. Suncloud Optics has sole discretion to determine manufacturer's defects. Polaroid is not affiliated with Suncloud sunglasses manufactured prior to 2006 (identifiable by "SCR" etched on the upper corner of a glass lens). Sunclouds manufactured before 2006 are not offered warranty or repair services and will be returned to the customer if sent in.
