what season?
here's some generic advice anyways.
for baselayers touching your skin?
usually wool. its antimicrobial and doesn't smell when not washed for a while.
wool's main downside for this is that it takes forever to dry and can be troublesome to wash in the field in some climates/weather.
in really hot weather its simply too hot for wool. synthetic mesh and frequent washing is the way to go.
in really humid weather synthetics and frequent washing might edge out wool.
shirt to throw over it not touching your skin?
completely depends on climate & weather. you don't really need this unless you're stopping in towns and wanna look normal-ish.
midlayer active insulation?
you want something very breathable when moving, that still keeps you warm, if you're in cold enough weather you need to hike with a midlayer on.
richfag flexer: alpha direct hoodie + ultralight nylon wind shirt (wind shirt must be used to regulate heat)
richfag flexer#2: airmesh hoodie from mountain hardwear (standalone)
cheap: polartec 100 fleece (standalone)
other considerations:
always wear shorts or shorts+leggings over pants if you can get away with it. might not wanna off trailing.
by the same logic, rain skirts > rain pants if needed.
if you need a rain shell make sure it has pit zips or fits loosely.
warm weather: loose fitting airy clothes, i usually buy my summer shit +1 size from normal
cold weather: tight fitting lofty clothes
