Yeah the builder of the helmet has only made 2 thus far (maybe doing another unsure at present).
The one I have is the original build which has a cast made from it, that much I do know.
The second helmet only had a working target light. Whilst this one as said 2 fans and light.
Each switch activates each item so in theory you could wire both fans to One switch and rework for a working visor. Though that would require new battery placement for starters.
However I actually like the visor down and anonymity that comes with it. So fans work for me.
Not sure of how heavy SWS helmets are, this one would equate to the same as a Motorcycle helmet so yes this form of inner head wear works very well and is indeed comfortable
I have a 24" XXL head size so works a treat for me.
I am hoping the prop builder will make another as I would really like to get another to turn into a REDWOLF helmet. Failing that Jason Brains in Germany does the Vac Form Airwolf helmet kit as another option for the REDWOLF helmet.
For Airwolf helmet this is certainly my Winner. Well till the day I can claim possession of a SWS one that is lol
Would actually love to compare side by side with a SWS.
