Soft turtleneck sweater, size M Fleece-lined, Fiber Heat for ultimate warmth. The part that touches the neck is made of the same fabric as the outside, but the inside is fleece-lined, making it soft and smooth yet incredibly warm. I bought several of these to wear at work, but I get too hot even in winter when I'm moving around, so I'm now using something a little thinner, which is why I'm selling this. Although thin, it's very warm. How about preparing for winter? I haven't worn it, but I have washed it once. I think it was around 2000 yen. Thank you for looking.
