When the weather report says who knows, the Lone Mountain, with its 3-in-1 design, provides peace of mind no matter what conditions you encounter. You can wear the shell alone in the rain; add the zip-out jacket for cold, wet weather; or slip on just the liner when the skies clear. Its 2-layer H2No Performance Standard nylon shell (51% recycled) with a DWR (durable water repellent) finish, is completely waterproof, windproof and breathable. A slick polyester taffeta lining (100% recycled) wicks moisture, dries quickly and glides over layers. Shell details include an insulated, two-way adjustable hood; a two-way front zipper protected by an external storm flap with an interior wind flap; a zip-through collar lined with microfleece; a microfleece-lined chin flap; adjustable cuffs with two snap closures and an adjustable hem to seal out dicey weather. The zip-out jacket attaches to the shell via the front zipper and snapped loops at the cuffs and neck. The jacket is insulated with a soft, efficient layer of THERMOLITE 100% polyester (92% recycled) to wrap you in warmth and stay toasty, even when wet. Smooth ¬º"-pile polyester fleece (70% recycled) lines the body of the jacket; sleeves are lined with recycled polyester taffeta. Jacket features include diamond quilting to keep the insulation from shifting; a full front zipper with a zip-through, stand-up collar and zipper garage; handwarmer pockets lined with microfleece and an interior right-chest security pocket with a zipper closure. Shell pocketing includes zippered handwarmer pockets (lined for softness) and a zippered internal pocket designed for headphone compatibility. It's also Fair Trade Certified sewn, which means the people who made it earned a premium for their labor. Hip length.
