Ergodyne 6811Z Rib Knit Hat with Zipper for Bump Cap Insert - Acrylic - Black

Made with stretchable, 100 percent acrylic, rib-knit fabric, this 6811Z Zippered Rib Knit Beanie is a perfect, cold-weather outfit accessory. Fabric creates a snug fit that keeps cold out. Stretchy material provides room for most head sizes yet conforms to your head to trap heat inside. Beanie is designed to fit under headgear for added warmth while working. Zippered compartment holds a Skullerz 8945 Universal Bump Cap (not included) to protect your head from bumps, scrapes, bruises and other minor injuries. Beanie is great to wear during work that involves cold weather or tight spaces where you are prone to bumping your head. Machine-wash to wear the next day.
