The Phenom SS features a carbon-Kevlar/fiberglass construction. It includes a wide, peripheral eye opening that can be used for open wheel or closed cockpit driving. Multiple exterior vents increase circulation to a redesigned interior. The interior has channels which not only cool the driver, but has additional channels which route air towards the shield, which reduces the chance of shield fogging. The Phenom SS has removable, washable padding that can be repositioned for a comfortable fit. All interior seams have been removed from areas where greater pressure is exerted on the head. The Phenom SS has been designed to accommodate a drink tube and an intercom system. Available in flat black only, sizes XS to XXL (new size M/L). The Phenom SS has Hans clips pre-installed, which can easily be removed and replaced with the FHR post of your choice. FIA 8859-2015 (with Hans posts installed) and Snell SA2015 approved (regardless of FHR posts installed).
