These are United Arrows pants with a slightly brushed lining. Please refer to the detailed photos of the size. They stretch well horizontally, but the waistband fabric doesn't stretch and is fixed in size. Therefore, based on the waist (listed size is 38), we recommend judging by the actual measured dimensions in the photos. The color is a stylish terracotta-like shade, a mix of orange and gray, giving it a muted tone. It's a color you sometimes see at United Arrows.
