WWII USN Anti-flash gloves

[Vertol]

Hello,

 

I've bought USN Anti-flash gloves whose seller's packaging indicated 1944 with the NXSX contract.

 

Does anybody know in which material those gears (gloves and hood) are made ? It seems to be cotton (smooth, and fibers burn), but I'd just want to be sure it is not asbestos, such as british anti-flash hood ...

 

For example in use, here are 2 picture coming from a post of dustin (http://www.usmilitariaforum.com/forums/index.php?/topic/289203-the-use-of-the-life-preserver-belt-usn/)

 

Thanks in advance,

 

Regards,
