Predator Shiznit The Shiznit can be worn with the visor front or back. When compared to helmets with longer visors, the Shiznit 1 1/2 ”(4 cm) visor provides sun protection and improved safety by reducing bucketing and roll back. The shell is made of high impact Ralvek® thermoplastic for increased stiffness and protection. A comfortable closed-cell waterproof EVA foam is used to dissipate impacts. For a locked-down fit, the Shiznit features the Croc-Lok® rear adjustor. Other features include rubber edging trim, top quality webbing and buckles, locking side divider and stainless steel chinstrap rivets. CE EN 1385 Fit Pads included
