J. Crew full zip Sherpa fleece jacket in Smokey Wisteria Lavender. Size XS. Preloved, but great condition with no visible flaws or damage. Yes, the sherpa fleece jacket is back and better than ever. Our take on the classic features real fleece from Polartec (the company that invented the warm, cozy fabric) plus cool details like a high neck, a slight drop-shoulder and contrasting zipper pulls and cuffs. Bonus: It's roomy enough to layer over your favorite sweater and we made it in shades from our archives.
