Hi i'm Victor living between different countries of South America like Argentina, Brazil, Peru, Uruguay because of my job, so my question is how can i know if my pair of glasses is original? Bought these last week, good vibs to yall

The Gascan is a simple pair, and thus easy to copy. The SKU doesn't appear right since the -01 suffix matches the Matte Onyx / Global War on Terror colorway, which was an Standard Issue release.

The Gascan is also different since it began its life when the SKU's were just ##-###, and converted to the OO9###-## standard later.
*Usually* the -01 is the plain ol' black option, so that appears to be used here without realizing that the original Black/Black was 03-471.

Thanks my friend to reply, with the info you give me i can go to the store and make my claim about my purchase, they assured me that theses glasses are complete original, this is my first pair of Gascan i have 2 pair more Pitboss 2 and Turbine matte. Any advice to buy original Gascan ?
