What kind of Chin-strap is this?

[Novacks1939]

Hi everyone,
I'm new here. I have hundreds of these from a government surplus auction. They appear to be chinstraps, but I can't figure out what type of helmet they belong to. Can anyone help?
Thank you!

Don't believe they are chinstraps. Look more of a utility strap, although not familiar with the silver colored "buckles".

If it was chinstraps you would only have half a chinstrap. No buckle

Good point, maybe it isn't a chinstrap at all.

I think it looks like some kind of compression strap, but for compressing what i don't know. I am sure somebody knows what it is

Canadian chinstraps for MkII, post WWII, IMO.
