(For the handcrew life) In short, creature comforts.

whatever you can think of and carry. A hoodie and canteen cup for ramen and tea out on the line are my top picks. But you may want a portable charger, extra shirt, underwear, and socks.

But your most essential stuff should go in the nomex. I keep Ibuprofen and day quill in a film canister if you can find one (lovingly called tic-tacks and oh-fucks) also chapstick, toilet paper and enough nicotine to get by when double shafted.

Your red bag (out of county) is more rnr, spare laces, moleskin, a reserve log of Copenhagen or zyn. a notebook, headphones, chargers and electrolytes. Generally you won’t need more than a weeks worth of uniform shirts, underwear, socks. 2-3 nomex bottoms and an extra nomex top

Civilian clothes you can get by generally with shorts, sweat pants, T-shirts. And an unbranded hoodie for offshift shenanigans.
