I'm planning a 80 day/1000 mile camino this summer. It will be long, and hot (but maybe cold in the evenings in mountainous parts?). I'm wrestling with my clothing system - trying to keep it lightweight and versatile, multipurpose, sun protective, temperature range appropriate, and long-lasting (80 days will put some serious wear on things, and I'd rather not rely on replacing items in Spain for reasons of limited options with regard to cost, weight, fit, pickiness on technical aspects, etc.)
My current thoughts:
2 skirts (Patagonia Seabrook)
3 tech shirts (2 short sleeve, 1 long sleeve cooling)
3 undies (6" boyshorts for skirt hiker anti-chafing)
3 bras
3 prs socks (lightweight trailrunning)
Will probably wear long sleeve tech shirt most hiking days, and wash it nightly or semi-nightly (it is antimicrobial & quick dry)
Will wear 1 skirt day & night, so it stays out of pack while "dirty" - then wash & swap it out every 7-10 days
Will rotate/wash boyshorts/bras/socks daily, changing after shower into the ones I'll wear the next day
Will wear short sleeve tech shirts evenings after shower, wash as needed
Will sleep in boyshorts & short sleeve tech shirt I wore that evening
Short sleeve tech shirts can also be worn in day for hiking, as needed or desired
I'll also have a long underwear set (black, merino, v-neck top) that passes for outerwear - for cool evenings & sleeping as necessary, and a lightweight fleece hoodie.
That's the current plan, anyway.
