Sparco Shield RW-9 hoods provide you with the highest level of breathability, comfort, and weather protection! Theyre constructed from a seamless, ultra-soft, stretchable material; in key areas, thin-stretch Nomex adds comfort and mobility, with double-perforated Nomex offering increased ventilation. A new filament design removes moisture as quickly as possible for added freshness. Sparco Shield RW-9 hoods only weigh 180mg, making them the most lightweight, fireproof "head sock" on the market. Choose the color you prefer, and layer up!
