This is a long-sleeved shirt from Pearly Gates. The fabric is a bit thick, like a thin sweatshirt. It's not fleece-lined. It felt just right for spring, autumn, and as an inner layer in winter. The size is listed as 3 (men's S), but I'm 170cm tall and weigh 62kg, and it fit perfectly under an outer layer. There's a small snag that's not very noticeable, which is due to use.
