Winter : we wear warmer clothes and always a waterproof jacket in the backbag. A base layer, a windproof jersey and long tights are ideal. Thick padded jackets are not recommended as they are very warm. Generally we apply the principle of onion, we wear 2-3 slim clothes (one above the other), instead of a thick and very warm, if we feel warmer we put out one or two of them. The warmer days we wear short jersey and an isothermal base layer but once the sun goes down we must wear a long jersey or our rain jacket.
