This is a John Smedley 24-gauge turtleneck. It cost around 30,000 yen. A burgundy color in the same size is also on sale. I loved it, but it no longer fits due to weight training. It's labeled as size S, but it feels like a men's M size. It stretches quite a bit vertically and horizontally. It has a good length and is easy to wear. The hem is narrowed, so it seems like women can wear it too. Shoulder width / Body width / Sleeve length / Length Length: 67cm Body width: 50cm Raglan sleeves, so shoulder width and sleeve length cannot be measured, but approximately shoulder width 50cm, sleeve length 65cm
