The new Glissade Insulator is a hybrid jacket that can stand alone or work as an extra layer, with its combo of fleece and Downproof Polyester Nail Head Weave with Spylon DWR waterproofing and a fortifying layer of 60g 3M Thinsulate insulation. Power stretch panels down the sides of body and arms and reflective details put this ski season esSentinel in a class by itself.
