The FMA version of the Ops Core Maritime kevlar helmet is a great replica. Made well, solid build quality and reasonably priced at around £60.00 from Helmet World. With a quick adjust harness set up, much like it’s real counterpart, it’s easy to get a comfortable fit. Now, for those of you with a larger head like me (mine measures in at just over 61cm), you’ll need to go for the L/XL size and even then you may find it a little too tight. The solution is simple though. Just remove the solid foam harness and chin strap and replace it with a standard H-Nape chin strap and get a foam set for the inside and the thing will fit like a glove. Perfect for those of you wearing MSA Sordins or other forms of cupped ear defence.
