Shell fabric: 15 denier nylon constructed with high tensile strength triple ripstop threads to give excellent tear strength and durability. DWR on the exterior of the fabric keeps moisture from accumulating.
Lining fabric: 30 denier nylon taffeta with a tight weave construction and cire finish for a silky smooth next-to-skin feel.
Footbox: 15 denier nylon constructed with high tensile strength triple ripstop threads to give excellent tear strength and durability. An ultralight waterproof/breathable coating on the back side of the fabric combined with DWR on the exterior means that the footbox breathes throughout the night and won’t retain moisture.
Insulation: Premium 700 Fill Power down treated with DownTek™ nanotechnology. This highly durable water repellency treatment on down clusters and feathers prevents wetting out and maintains insulative properties of down in the presence of moisture.
