The Women's Patagonia Classic Microdini Fleece Vest is a light, ultrasoft fleece vest that is made from 100% recycled polyester microfleece. The Micro Vest is comfortable, supple, warm, and extremely breathable. This light weight and moisture wicking Patagonia fleece is made from more recycled polyester than any other microfleece, so it's as good for the environment as it is your body temperature. The Micro D features a full-length zipper that extends through a stand-up collar for soft warmth and protection. The Womens Patagonia Micro D Fleece Vest is a great choice for wear on a cool day or as a layering piece underneath a shell when the weather turns.
