Polartec PowerShield is the original soft shell fabric technology that combined breathable comfort with high performance weather resistance. This family of fabric styles has a nylon or polyester face that is water repellent, wind resistant and durable. The interior is finished with an insulating layer of fleece, Power Dry (high loft, classic or micro) or in the case of style 6617, there is no inner fabric, it's just the membrane. Style 6617 is intended to be lined with Polartec Alpha or Alpha Direct. PowerShield fabrics block 98% of the wind while allowing some air movement for increased breathability. Power Shield Lightweight is our lightest style as the back fabrics are either lightweight Power Dry or microfleece. These make great summer shell jackets or can be used in a layering system when the weather gets colder.
