Functional insulation for energetic winter activities. The icy Creek is a fiber insulated jacket with very good wicking performance. This makes it good to wear on its own or as part of a layering system. By using the system zip, it is quick and easy to zip it into a compatible outer jacket. It incorporates our micro Guard max loft synthetic fiber insulation, which ensures good heat retention and good moisture management performance.
