usually u can tell when you put them on- the elastic on the sleeves and how they feel and look at the bottom. Most importantly the stitching on the tags and logos.
if you can just buy a real one its well worth it, if not check on craigslist for a bootleg one ($50-$75) so you can see it in person and atleast see if you like it.
thanks folks, ive noticed some of the shit u wrote right there before u posted , but thanks anyways. i was tryin to see if there was any info on the tags i should be lookin for, ill read the link once i get off from work. thanks again
