Having worn man rucks, backpacks, and day packs over many miles, I can you tell it's because he's fucking fat. It's doesn't help that I'm sure it's some straight temu shit. I could wear all our packs over our body armor when I was in, including ones I bought myself. These weren't slick cool plates carriers either. I'm talking old school interceptor vests with thick ass E-SAPIs.
Even all the packs I own now, except for small summit packs and the like, could fit over my body armor if I ever got brain damaged enough try. Phil is so fucking fat he cannot wear normal people gear. The half inch worth of mall ninja bullshit isn't' to blame. It's the 250lbs of extra blubber he carts around.
