The draw string is a good indicator on these, they are usually off white/cream colour, and if not, then they are a colour that very closely matches the shorts. The colour of the drawstring is just way off everything.
The ape head on the tag is also a little wonky.
When you look at the back of the shorts there is no ape heads in the camo at all. This normally isn't a good indicator of an items authenticity as the shoes, hats, and heads of shark hoodies sometimes have no ape heads, but in the fabric used on the shorts there is always some amount of ape heads just given how much fabric is needed... You'll noticed a straight repeating line of ape heads in authentic camo.
