Milwaukee MIL-48-73-4545 BOLT Cooling Skull Cap


Our BOLT Cooling Skull Cap is designed to be activated by water and features microfiber technology to keep you cool on the jobsite. This sweatband can be quickly activated by running or submerging it under water for 30 seconds for full absorption. Wring out any excess water and repeat when dry. When activated, the Cooling Skull Cap will wick away moisture and heat giving you up to 4 hours of cooling time. Designed to be compatible with MILWAUKEE Safety Helmets and Hard Hats, our Cooling Skull Cap will provide long-lasting comfort with its comfortable, 4-way stretch material and is part of the BOLT Accessory System which allows our users to secure accessories simultaneously.
