FAST® SF Super High Cut Helmet System ■ Super high cut, ballistic shell made of a hybrid composite of the most advanced Carbon, Unidirectional Polyethylene and woven Aramid. ■ High performance evolution of the Ops-Core FAST MT Super High Cut Helmet, with an 8% weight reduction, while maintaining compatibility with FAST head borne accessories. ■ Super high cut shell geometry extends critical coverage over the rear occipital lobe without load carrier interference, and optimizes weight distribution for increased stability, integration, balance, and improved comfort. ■ Ear cut geometry is 16 mm higher than the FAST XP High Cut shell shape, allowing for clearance of larger headset style communication devices. ■ Super High Cut Skeleton Rails offer lower profile with a 30% weight reduction from FAST MT Super High Cut Rails. ■ Features a lightweight Modular Bungee Shroud (MBS) which reduces snag hazards and interference. Integrated carabiner clips improve NVG retention, stability, and reduce interference with rail-mounted accessories. ■ Molded liner features proprietary recessed groove, accommodating over-the-head communications headsets with no interference or user discomfort, and ability to doff and don helmet without removing the headset. ■ Interior of helmet features expanded polypropylene (EPP) liner, offering enhanced impact protection, and molded-in vent holes provide increased airflow and reduce heat stress. ■ Available with three suspension/retention options.
