>>2380477>>2380691The performance of clothing is significant between low wool and high wool concentration. A wool jacket should for example be of 100% felt/wadmal wool so that it resists water properly, a mid layer can be as low as 70% wool before it starts to perform like a plastic sweater.
Base layer doesn't matter too much, but the more wool you have in the fabric mix the more resistant it is to smelling shit.
tldr get as close to that 100% wool on the tag as possible.
