The CG634 is made of Aramid (Kevlar) and has a minimum v50 of 634 m/s (compared to the PASGT's 610 m/s).
The CG634 has a somewhat similar shape and is sometimes mistaken for the later United States Army's MICH TC-2000 Combat Helmet However NOT THIS MODEL! This model has been modified by Northern Combat Solutions to include the modern attachments and a high-cut frame!
