Hi, I'm in the process of buying cold weather running clothes. I live in the south, so the coldest weather I will be running in is 30s-40s. I run at night so it will be colder. I honestly will not be running that much and think I can just buy a cotton or cotton/polyester blend hoodie. But I never see people running in hoodies anymore, all I see is people running in fancy Nike half zips and jackets that supposedly have a lot of "tech" like thermoregulation etc. Anyone here still just run in just plain hoodies???
