The HANS Model 20 is designed for most upright seats in sedans, sports cars, stock cars, and midgets. (Some very barrel-chested drivers in these cars may find the Model 30 more comfortable.)
The Professional Ultra series is constructed of high-modulous carbon fiber with a lower, rounded backboard for light weight (approximately 1 pound). Includes Vision Advantage Plus sliding tethers and FIA-Approved* M61 quick-release anchors. SFI 38.1 approved, FIA 8858-2010 homologated, and accepted by all major auto racing organizations (including NASCAR, FIA, IMSA, NASA, and SCCA).
* 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.
To determine the correct size, measure your neck and follow the chart below.
|Neck Size* ||14" to 17"||16" to 20"|
|HANS Size ||Medium||Large|
* Drivers with highly developed neck and trapezuis muscles may require one size larger than their neck size alone would indicate. Comfort is always the deciding factor.
