answer:You tightly roll each piece of clothing up and lay them in with a spare pair of underwear and a T-shirt and your toiletry kit on top. Rolled properly, the clothes wrinkle only slightly and you can fit an amazing amount of changes in there. You can fit a shirt and a pair of pants on each layer. I stick a pair of socks in one pocket of the pants and a pair of undies in the other so they won’t get lost, but you can just lay them in with that day’s clothes like the spit and polish guys. Separate each layer with a T-shirt. Remember: toiletry kit on top. Welcome aboard, kid. You’re in the Navy now. This is how the Army does it, evidently And welcome to ask-public.
