I’ve been backpacking (wilderness) since I was 8. I’m 51 now. I’m so used to making do with very little it’s easy (and yet people are always amazed at the comfort level!) Here’s what I took for a fall trip to France for example, last year for 22 days:
One sleeveless shirt (blend with stretch) -black
Two long sleeve shirts ( one cotton/modal, one lightweight merino wool, which was a quarter zip neck for venting/neck protection)- grey/dark grey
One lightweight merino wool sweater, still thinner but warmer than the zip neck -grey
One rayon blouse/shirt that looked a bit nicer -Black with black/white floral sleeves
One pair black skinny jeans that were so dark they could double as nicer pants, one pair darker lightweight jeans
3 pairs no-show socks wool blend, one thin mid sock merino wool
5 pairs wool thong underwear 1 pair wool bikini for sleeping. I gave up bras several years ago, but occasionally take a lightweight no wire from Negative underwear that weighs nothing.
Wind resistant woven fleece sweater with hood (looks nice but is excellent for warmth and wind
Waterproof lightweight trench coat with hood
Nike phantom sneakers black/white
Worn: one black lightweight merino long sleeve and one pair light blue jeans cropped above ankle, black thin arcteryx synthetic vest excellent warmth very lightweight
Adidas original retro sneakers camel colored suede
Umbrella, meds, contacts (dailies) moisturizer, face wash, toothbrush/toothpaste combo (bought at REI) small cosmetic bag with tweezers small amount of makeup. Collapsible silicon diffuser (curly long hair), guide book, maps.
I don’t take body soap, or shampoo/conditioner. First, there’s always soap wherever I stay. If there’s not one night, water will get me clean enough until the next day. I don’t wash my hair that often since it’s long curly and dry. If there’s not enough shampoo in the room, we’ll buy a $3 bottle of each at a drugstore/pharmacy/grocery-partner often takes his own travel size. I’ll throw it away when I leave or leave it. I use hotel lotion. I took running shorts and a running shirt too (Nike Phantoms stand in for a few maintenance runs)
In my small personal item goes any snacks, book(s) ID/passport, eye drops, tic tacs, plane collapsible pillow/eye mask, Burt’s Bees lip balm and empty water bottle.
I’m probably forgetting something but probably not anything major. Hopefully this is helpful. Clothes can be adjusted for season.
As mentioned, I do laundry at least once, and use packing cubes (but only need two). I can wash my underwear in the sink, it’s dry FAST.
