For military/tactical type systems, I'd check these top brands...
Blackhawk, 5.11 Tactical, CSM Gear, Crye Precision, VooDoo Tactical, TangoDown.
Blackhawk was started by a former SEAL. Crye Precision markets the Multicam digital camo & a high tech helmet for SWAT-spec ops(I call it a hockey helmet
).
