Patagonia Retro Pile Pullover

Patagonia says:
Made from double-sided shearling fleece, Retro Pile fabric provides easy-wearing warmth for any cool-weather venture, thanks to a soft, fuzzy exterior and a smooth, skin-friendly interior. The Retro Pile Pullover's center-front zipper extends to the top of the stand-up collar for quick venting of excess heat, and the set-in sleeve design allows full mobility and compatibility with pack straps. Flat-seam construction throughout reduces bulk and helps minimize seam chafe. A zippered left-chest pocket holds your daily necessities. Soft spandex trim finishes the cuffs and hem. It's also Fair Trade Certified(TM) sewn, which means the people who made it earned a premium for their labor.
