A jacket insulated with synthetic fiber has, for many, completely replaced the use of a thick fleece: a lightweight insulated jacket is warmer and wind doesn't blow through it. Thanks to the PrimaLoft Silver insulation fiber, this jacket is also nearly unaffected by moisture, as the fiber doesnt collapse in damp conditions nearly as much as down does. When used under a shell jacket, the shell can be ventilated without worrying about wind reaching your skin.
