Quarter zip polyester women’s base layer

Women’s base layer, size small, polyester. The inside of the fabric is stark white, so some areas of the inside have started to brown a small amount, but it is not visible from the outside of the garment - see photos. There is also some pilling around the thumb holes and cuffs - see photos. I forget the exact fabric rating, but it’s at least upf 50 Sun protection. Great for ski, golf, bike, hike, or gardening! 👩‍🌾
