Exceptionally Unique Garb
A distinctive uniform, distinct from that of the rest of the Navy, is worn by submariners. The emblems and colours of the United States Navy have been updated, yet they may still be recognised by their traditional appearance. Overalls of a dark blue colour are worn by members of the submarine crew; however, these particular overalls are made of a lint-free polyester.
Is there any way we can make sense of what’s going on here? On board the submarine, the air filtration system may become blocked by lint at some point. This item of clothing is also referred to as a poop suit, which is another hilarious name for it. Poop suit is an acronym for “poop suit.”
