Haiving had several hundred square meters to put stuff it is definetly hard work to reduce one selfe to a backpack. Well a back pack one can still carry. My polar equipment for the siberian winter definetly takes some space and today at warm spring temperatures felt weird to wear as a test. My russian friens where more worried that I have slippers for the train. So I have my slippers ready as well to steam through at -40° C ( -40° F).
