Nylon stockings. Use women's nylon stockings (cut, of course) as arm or leg warmers and save on a long cycling trousers - an enormous weight and space saving. Don't let prejudice interfere with your principles. If there's not a trace of transvestite in you, wear them under regular trousers or rain pants. They are usefull as sun-screen for the arms and legs too: you can forget about that mix of sweat, sun-screen and dirt on your body, that you were so proud of during your "self-sufficient" stage.
