Stand 21 - Carbon Fibre.
They call this HANS unit the "ULTIMATE” for a reason! Super slimline and Super light. Yes it’s the dearest on the market but your necks worth it. The ULTIMATE offers a reduction of its physical thickness to below 2 mm around the back of the unit allowing more room for helmet-to-seat (or headrest) space. This is a must for applications where roll cages might be directly behind drivers head like used in funny-car / Dragster roll cages.
This 20° ULTIMATE can be used in upright applications like Sprint cars right through to lay-back vehicles like drag racing Dragsters and Funny-cars.
