ATHLETA Athleta Ultra Shell Warm-up Jacket Navy Jersey Fleece Lining Size M Thank you for viewing. Size: M Features ATHLETA's original high-performance stretch material "BomFilter" with a 3-layer structure. There are no noticeable stains, but it is a used item, so there may be oversights. I purchased this item this month, but I already had the same one, so I am selling it unused. The fabric is thick and blocks wind and cold, so it makes a difference just by wearing it on windy days or cold days. I think it looks cool and is a very good product.
