overview
Racing Optics Speedstack-7 Tear Offs for HJC and some Simpson helmets (see list under tech tab) are a 2 mil stack of seven tear offs laminated together, installing as a one-piece unit, and providing optically clear visibility, low reflection, and eliminating fog between layers.
By optically laminating the 7-layer stack, all air is removed from between the layers, eliminating any reflections. The 7-layer stack has the same optical clarity as a single 2 mil. tear off!
Sold in a package of 5 stacks. Each stack is composed of 7 individual tear offs laminated together (35 tear-offs total).
