The HANS Model 30 is designed for most layback seats in formula cars and sports racers. Some very barrel-chested drivers in sedans may also find the Model 30 more comfortable than the more upright model 20.
The Professional series is constructed of high-modulous carbon fiber for light weight (approximately 1 pound lighter than the Sport series) and includes Vision Advantage Plus sliding tethers and FIA-Approved* M61 quick-release anchors. FIA 8858-2010 homologated, SFI 38.1 approved, and accepted by all auto racing organizations (including SCCA, NASA, NASCAR, IMSA, and FIA).
* When installed in an SAH2010, SA2015, FIA 8858-2010, or FIA 8859-2015 helmet. M61 anchors are SFI-approved when installed in any other helmet using the included nutwashers.
