This 3-in-1 style jacket has a waterproof outer shell and an synthetic insulation liner. The outer shell is made using Montbell's original waterproof breathable material, SUPER HYDRO BREEZE®. The liner is filled with EXCELOFT®, a synthetic insulation which won't lose its insulating properties when wet. Either jacket can be used by itself and when used together can be used for winter alpine climbing and other winter activities.
