I prefer camping, and my husband prefers fishing. Usually we successfully combine it. But I don't mind when my husband goes to the lake with friends, but in winter it always ends with a cold. I don't know how people fish in the winter without harm to health. He has a warm jacket, thermal underwear, but he still freezes. I read on hikezone an article about shoes for winter fishing, I think to give him good shoes for his birthday. Perhaps you can advise something?
