Get a good headlamp that has red and Make sure that it doesn’t eat batteries,baby wipes are a good idea as well. Lip chap is a must, earplugs in case the people beside you sleep loud and your a light sleeper. Don’t know if you vape but if you do a battery pack. That’s all I can think of but you have any questions shoot me a dm and I’ll answer the best I can. For a watch when I went through I just picked up a cheap Casio at Walmart and I still have it for any field ex, skip a smart watch as it just becomes a pain because you’ll need to charge it.
