The EVO Button Cutaway Kit.
Developed by Sky Shot and SkySystems USA for the EVO helmet, but will fit any other helmet with a chincup. The button cutaway system allows for a fast and effective chincup release.
The EVO Button Cutaway can be used in an entanglement emergency to release your helmet from your head. This spring-loaded cutaway system allows you to cutaway your helmet in case of entanglement.
Note: Chincup not included, but chincups are available separately from ChutingStar.
