I wear light weight merino and syn briefs under mid weight mountain pants. I carry an extra Primaloft jacket that I wrap around my legs on stands and while glassing and sit on a 1/2" ensolite pad cut to 1'x2'. The jacket weighs just 1 lb and stuffs the size of a 1L water bottle. I like zip off down pants also but the jacket is cheaper and does double duty.
