Why: Military-inspired gear that doesn't include a shit ton of camo is practically kryptonite to the modern hypebeast.
If it's military-inspired and doesn't have camo, then hypebeast aren't going to take the time to try and understand it. Heritage Research has actual history in almost every piece they produce, so they certainly aren't ones to say, "oooh, this is trending right now. We should do our own spin on it!" THAT MAKE HYPEBEAST ANGRY.
