This is a Patagonia cut-and-sew top. 52% Merino Wool 48% Polyester Size: Women's M Measurements: Width (front): 41cm Width (back): 48cm Sleeve Length: 61cm Length: 62cm There is some pilling due to wear. Merino wool is warm and has strong antibacterial properties, so washing lightly every 2-3 times is sufficient. It became popular for outdoor use because it inhibits the growth of bacteria and suppresses odors. It has a not-so-deep V-neck. It's a women's M, but it actually fits like a M to L. I usually wear L and it wasn't tight. It's a soft and warm cut-and-sew top. Purchased at the Patagonia flagship store. Thank you. ※ I have a cat. I will be careful when packaging, but cat hair may get mixed in. Please refrain from purchasing if you have severe allergies. ※ There are individual differences in the perception of used clothing.
