Occunomix Tyvek Quilted Nylon Head Protector has three layers of protection to keep you focused on the job when wind, rain, and cold threatens productivity. The quilted nylon outer shell sits over a 4 mm. foam center and is lined with soft, odor resistant fleece to keep you insulated and dry. Built-in interior ear pockets can hold disposable warming packs and are lined with Tyvek to provide an extra barrier against freezing temperatures. A short elastic forehead strip and chin strap keep the hood anchored, while a reflective strip above the back of neck adds visibility on short, dark winter days or in low light conditions. (Also available in 2mm foam: Occun-RQ300)
