These are the initial windproof jeans from Uniqlo's "UJ" jeans brand, which pioneered functional bottoms. Unlike the recent fleece-lined types, these feature a smooth interior. • Three-layer windproof technology: A special windproof film is laminated between the denim outer layer and the lining. While they look like authentic denim, they shut out cold winds. • Sleek silhouette: Because they are not fleece-lined, they don't bulk up and the leg line looks beautiful. They are less bulky and can be worn for a long time, from the chilly days of spring and autumn to the dead of winter. • Detailed craftsmanship: The outer fabric is made of sturdy 100% cotton. They have a tough construction, typical of the UJ line at the time, that develops character the more you wear them. Product Condition These are rare, early models from about 5 years ago, but as the images show, the tags are clean and the fabric still has a good firmness. The indigo fading is just right, giving them a vintage feel.
