1-ply? 2-ply? Good? Not so good? I have seen this at the regular store as well as the Last Call. They come in a variety of sizes and styles. Cashmere is very soft, but it's hard to tell how durable. Some are labeled "superfine" others "luxury cashmere" and still others "private label" but all are listed as made in China. Prices are ~ $200-700 retail; the Last Call discounts make them seem a relatively good value. Thoughts?
