The Chill-Its 8937 Performance Cooling Baseball Hat features an evaporative cooling sweatband and lining that wicks sweat and moisture when worn dry and provides immediate cooling relief when worn wet. Vented back panels increase airflow for breathable comfort, and an anti-odor treatment makes for fresh all-day wear. The black reflective logo, piping and hook & loop closure enhance visibility in low-light conditions while remaining low-profile for daytime wear. One size fits all, this cooling hat features a hook & loop closure for an adjustable fit. Ideal for construction, landscaping, roofing or anyone working in the heat. It can also be used to reduce the risk of heat stress for outdoor recreational activities.
