When wearing a BDU of the Rolled High Dirty Variant, if you look down you'll notice your legs from the waist down have a faded out blurry quality to the texture. This only effects all versions of the Rolled High Dirty variant, it does not effect the non dirty version or the version of rolled high dirty with gloves. Just to be clear, it's specifically the Rolled High Dirty version, all camo patterns. Not the non dirty rolled high or either version of the rolled high that has gloves.
It's very noticeable on the OD pattern variant, though it exist on all the camo versions as well.
