Here’s my setup for staying warm for two hours in an indoor skatepark placed in an uninsulated concrete and steel barn at minus 4 celcius.
Legs:
Two pairs of thin woolen underwear. Both pairs are full of holes, but the holes overlap, so I’m covered everywhere. One pair of thin, loose, elastic chinos and finished up with a pair of thermal work pants.
Torso:
Two thin woolen undershirts, one thin woolen sweater, one big cotton hoodie, and finished with a down jacket.
Thin woolen socks in a pair of half cabs, a scarf, beanie and fingerless gloves.
When I layer up, it’s important to me, that inner layers are thin and made of wool, and every garment needs to be oversized, so I that nothing crawls anywhere when I move.
