Gray full-zip hoodie with Dri-FIT function, size XS, comfortable to wear. - Brand: Nike - Color: Gray - Size: XS - Material: 100% Polyester - Features: Dri-FIT function - Design: Full-zip, with hood Thank you for viewing. The inside is fleece material. The inside of the hood is mesh. I think it's a material that can be used except in midsummer. It's also the perfect thinness to wear over a short-sleeved shirt in the spring. I think it can also be used as a cold weather measure by wearing it under a thick outer in winter. Although there is a feeling of use, I don't think there are any noticeable stains or pilling on the surface. I think it's still in a condition that you can wear.
