The Columbia Whirlibird Interchange Jacket is three great jackets in one! Wear the waterproof, breathable, and critically seam-sealed shell in the spring rains; wear the warm, water-repellent thermal reflective liner in the fall chill; or zip them together to keep warm, dry, and comfortable in fluctuating winter conditions. Omni-Heat thermal reflective technology (in the liner) utilizes little silver dots to reflect and retain body heat for unparalleled warmth. The Omni-Tech shell jacket is crafted from ultra-durable nylon Legacy Twill fabric with a smooth nylon 210T taffeta lining. The shell features a removable, adjustable hood; a waterproof, full-length front zipper; underarm zippers for ventilation; hook-and-loop adjustable cuffs; zippered chest and hand pockets; a goggle pocket; an interior security pocket; an adjustable, snap-back powder skirt; and a drawcord-adjustable hem with a drop tail. The liner jacket is made of smooth polyester microfiber fabric, packed with 80 grams of Microtemp XF II polyester insulation, and lined with polyester Microtex Light fabric. The liner features a mock-neck collar, full-front zipper, and zip-secure hand pockets. Regular fit. Imported.
