I used to wear a screen accurate balaclava to hide my neck, but found it hot & uncomfortable & it further blocked my hearing. Taking a cue from Boba I substituted the head covering for a neck seal only. Wayyy more comfortable & cooler which is important in an already warm costume. I'll be putting a couple of these in the Cargo Hold or you can pm me for info if interested. It does up with velcro in the front (or back if you like) & I sewed mine permanently into my costume.
Pics are up now. This is the prototype & I am going to make a small modification to it after reading some of the comments here. Stay tuned.
