I already bought another hood before from another FSBE II collector. He used it for his contemporary FR look. The hood is made by Fire Brigade Mfg. It's a nice piece of kit, but it's a heavy hood, made with thick material. I must say that the Koman hood is much lighter and more comfortable to wear.
The following hood is a CVC hood or a Combat Vehicle Crewman hood. This hood is even thicker than the Fire Brigade one and is too small for me unfortunately. I bought this to replicate the look of the Fire Brigade one. But as it turned out, it wasn't only too small, but it didn't look anything like it. So I kept it for the "collection", as they're not even worth selling.
Then the Marines started getting their FROG (Fire Resistant Organizational Gear) gear. So I bought a first gen FROG hood.
And also a 2nd gen FROG hood with mesh top for extra comfort when wearing a helmet.
Last is my Under Armour Heat Gear hood. Unlike the other ones, this one doesn't offer any flash protection. It's more for looks than anything else. I bought this one first, just to match up with the CB color of the FSBE II gear.
I do have some more hoods, but they're the nameless airsoft type of deal, not worth posting.
Family picture for color comparison!
