The Patagonia Men's Windsweep 3-in-1 Ski Jacket is adaptable to the full range of mountain or town weather, it provides exceptional performance in three ways. You can wear just the shell for rain protection; just the liner as a lightweight, insulated midlayer; or wear both together for a warm, insulated, waterproof/breathable jacket that cuts through snow and cold. We make the H2No® Performance Standard shell from a 2-layer blend of 80% nylon/20% polyester. It has a waterproof/breathable barrier and a DWR (durable water repellent) finish to manage moisture, both inside and out. A wicking mesh liner adds comfort, versatility and a smooth glide when used in tandem with additional layers. The helmet-compatible, 2-way-adjustable hood has a drop-collar design for exceptional coverage without impeding visibility. Interior storm flaps cover the front zipper and create a zipper garage at the chin, which is lined with microfleece for skin-friendly comfort. Lightweight and compressible, the zip-out liner features 150-g Thermogreen® insulation for warmth; a windproof, 100% recycled polyester taffeta shell with a DWR (durable water repellent) finish; and diamond quilting to increase heat-trapping efficiency. Pockets on the shell include two handwarmers and one chest pocket that close with watertight slim zips to reduce bulk and weight. Liner pockets include two handwarmers (lined with soft microfleece for comfort) and an interior security pocket for valuables. The zip-out jacket attaches to the shell easily with center-front zippers and snap-loops at cuffs and back of neck.
