This is a reproduction model made in the USA using CONE DENIM (formerly Cone Mills) White Oak fabric, which has become rare these days. Only the letter and hang tag remain. Unworn and unwashed. 66501-0008 ~About 501XX 1966 Model~ In 1966, the excellent quality of Levi's jeans was widely recognized, and the "XX" designation, which meant durable denim, was decided to be omitted. On the paper patch at the time, the new and old product numbers "501" and "501XX" (in smaller letters) were listed together to avoid confusion, and this is a major feature of the model, now also known as the "66 model." The hidden rivets on the back pockets were replaced with bar tacks reinforced with thread, and a new flasher was adopted to indicate this. Details such as the coin pocket being changed to a triple-stitched hem were also changed. Currently, there are no American-made LVC (Levi's Vintage Clothing) products, and only those made in Turkey, Bulgaria, and Japan are mainly available. Also, as mentioned at the beginning, this is made with the now-rare CONE DENIM (formerly Cone Mills) White Oak fabric. I have outgrown them, and I would like to pass them on to someone who understands their rarity and will wear them.
