Linear, projectile and rotational testing conducted at independent third party laboratories adhering to NOCSAE and ASTM standards for new helmets. Helmet testing comparison featured standard unprotected head forms and head forms with 2nd Skull® caps to measure variances in Severity Index, Angular Acceleration and Peak (g) improvement. For non-helmet activities, standard head forms were tested against head forms with 2nd Skull® headbands to measure variances in Force Improvement.
