The Oakley SI Cotton Cap offers a classic, low-profile tactical baseline look engineered for high durability and secure all-day comfort. It is built from a high-quality cotton twill blend blended with elastane to provide an adaptable, seamless stretch-fit structure. The front panels feature a functional hook-and-loop morale patch panel decorated with subtle, tonal Oakley ellipse embroidery for secure patch customization. To combat heat and maintain peak freshness, it incorporates an integrated O Hydrolix moisture-wicking sweatband that rapidly pulls perspiration away from the skin. The professional "Worn Olive" finish provides a versatile, non-reflective aesthetic tailored perfectly for tactical range wear, military personnel, and everyday off-duty utility.
