IMHO, that would have to be...comfort, quality and accuracy. Mr's TK409's neck seal is very comfortable, very well made and looks very accurate. Plus the materials used add to the comfort...the ribs "look" kinda like rubber, but there's not a trace of rubber in them. I love it
Next to my helmet, everyone always asks about my neck seal..."wow, it's just like in the movies." is usually what I hear all the time.
....I'm having my mother in law, who's a professional seamtress, trying her hand at making one....she doesn't think it'll be that difficult. She fabricated my Vader capes and did a fantastic job.
Gonna try a few different materials...cotton/poly blend, Lycra, etc......if it works out, I'll post pix and try to get her to make a few for sale....
Thanks for the nice compliments guys. Mrs. TK409 says she will make more if you like. She had taken a break for the baby a couple months ago and I had kind of hoped she would be done for good. But she actually kind of likes doing it. Your nice emails and feedback is what brought her out again. You can PM me or email at the website. http://www.tk409.com/tk409.html
