Patagonia Synchilla Snap-T Pants

Patagonia.com says:
Invented for those who can't migrate south to escape winter, our Synchilla(R) Snap-T(TM) Pants are soft, warm and livable. They're made from plush, 100% polyester fleece (80-85% recycled) that dries quickly, wicks moisture and is smooth against the skin. With an elasticized waistband, exterior drawstring and spandex binding at the cuffs, they perform equally well when worn alone or under shell pants. On-seam handwarmer pockets and a classic rear Snap-T pocket hold life's little necessities. Inseam (size M) is 32".
