The Chill-Its 6661 Universal Hard Hat Brim with Neck Shade attaches to hard hats and safety helmets to shade your face and neck for protection against sun damage. Flexible, full brim shade features a silicone-lined elastic interior to securely grip and attach to most hard hats and safety helmets. 20" wide panel shade with UPF 50+ protection extends down (9" long) for complete back-of-neck coverage. For a customized fit, the neck shade can be rolled away and snapped into storage when not in use. Darker-tinted underside of the brim helps to reduce excessive glare from the sun. High-visibility color keeps workers safe and seen. Handwash as needed and hang to dry. Hat brim and neck share are nonductive for safety when working around electrical environments. It is ideal for those working in sunny environments where shade is needed when wearing hard hats or safety helmets, including construction, roofing and landscaping. Brim is 3-1/4" deep in the front and 5" in the back.
