The REV is a compact, lightweight restrainst system designed to be extremely effective at controlling the head and neck in crashes where the driver sees big negative g-forces. Using a proprietary single tension-neutralizing tether (TNT), the loads under impact are distributed through four different load paths. This unique system offers an equal distribution of forces under impact. This system also offers a full range of head motion and side and angular impact protection. All REV packages include the quick release helmet hardware, carry case, tool kit, decals, and a bonus Flexfit hat size L/XL
The small 2" & medium 2" works ONLY with 2" belts. The medium 3" & large 3" works with BOTH 2" and 3" belts.
