Product catalog summary
Specifications Overview:
The document outlines the specifications for the FAST® SF Super High Cut Helmet System, a high-performance tactical helmet designed by Ops-Core. It is a lightweight, ballistic helmet made from a hybrid composite of advanced materials, including Carbon, Unidirectional Polyethylene, and woven Aramid.

Shell Construction and Design:
The helmet is available in sizes Medium, Large, X-Large, and XX-Large, with a shell thickness of 0.220 inches (5.58mm) and an areal density of 1.22 lbs/ft² (5957 g/m²). The design features a super high cut for enhanced coverage and compatibility with headborne accessories. The ear cut geometry is 16 mm higher than previous models, allowing for larger headset clearance.

Performance and Testing:
The helmet is tested for ballistic performance with various projectile types, achieving minimum V50 velocities ranging from 1,750 ft/s to 4,200 ft/s. It offers blunt impact protection with a maximum of 150 g’s at 10 ft/s and compression resistance under specified loads. Environmental resistance includes temperature extremes, flame resistance, and seawater exposure.

Features and Accessories:
The helmet includes Super High Cut Skeleton Rails with a 30% weight reduction, a Modular Bungee Shroud for reduced snag hazards, and an interior expanded polypropylene liner for impact protection and ventilation. It is compatible with over-the-head communication headsets and offers three suspension/retention options.

Weight and Sizing:
The shell weight varies by size, ranging from 1.39 lbs (630g) for Medium to 1.72 lbs (780g) for XX-Large. The system weight, including suspension/retention options, ranges from 2.25 lbs (1019g) to 2.40 lbs (1089g).
