I got a helmet but the the sticker is missing as to who made the helmet.
Helmet marking are
08 in a circle––-I take this as the year is was made
XL - 1––––-It is an XL but I'm not sure what the 1 stand for
SDS–––– I have now been told this is from Specialty Defense Systems
I just need someone to confirm this.
I guess everything you said is correct.
as for the number (1) next to the size (XL)... I think it's the depth of the helmet.
