Insulation can be achieved in several ways including high quality goose down, fleece, and high loft polyester. Down has the highest warmth to weight ratio but this loses its insulation properties when it becomes wet. Fleece is made from 100% polyester and is particularly good at keeping you warm when wet. Fleece is softer against the skin whilst still maintaining excellent performance characteristis. High lofting polyester is a synthetic insulation material which compresses like down but is warm when wet and quick drying so it is better than either goose or duck down when used in damp weather conditions.
