This is a thin fleece from Mountain Hardwear. I don't know the model name. It's a slightly darker brown than in the photos. - Brand: Mountain Hardwear - Color: Brown - Design: Zip-up, logo embroidery - Material: Fleece - Style: Long sleeve Thank you for looking. Gender...Men's Features...Warmth/Cold protection I usually wear S or M, and the size is just right. It has been used to some extent, and the cuff of the left sleeve is detached. Otherwise, I think there are no holes or noticeable fraying.
