Durable synthetic fiber, black long-sleeved shirt with a half-zip. - Brand: patagonia - Color: Black - Design: Half-zip - Sleeve Length: Long sleeve - Material: Synthetic fiber Thank you for viewing. Size: XL (LL) I used this as a base layer for skiing and snowboarding. I've used it 3 or 4 times, and it has pilled a little after washing. Please refrain from purchasing if you are sensitive to this. I think the overall condition is good as it has been used only a few times. It has a long zipper on the chest, making ventilation easy and convenient. The collar has a slightly high design. I will be unavailable to ship from January 13th to 16th and January 20th to 24th. Thank you.
