Was looking for some stretch dwr pants but are those types not suitable for town wearing in winter? Are they too cold? I came across the back forty pant from Sitka that 47 % cotton 37 spandex 16% cordura. Would those be better? I wear shorts most of the summer but need pants sometimes too. But I need the pants also to be viable in winter time as well so that's why I was wondering if pants like prana Zion, corrugate guides or the nylon spandex types are too cold just to wear while running errands or shopping in town during winter
