This is a set that feels warm, like fleece lining. Both items are size L. Please refer to the images for the materials. I've worn them about twice. I found a white vertical line at the end of the image, possibly from storage. It's not noticeable from the front, but it looks whitish from the side. It's not mold or dirt. I don't see any other issues, but I would appreciate your understanding as these have been stored at home. The set is a calm pink and navy blue, perfect for school or training. This is an authentic product.
