These are thin windbreaker pants. The lining is mesh, extending to about knee length. As shown in the photos, there is some wear on the seat of the pants (photo 6). There is also wear on both calves, as shown in photos 7 and 8. The tag has been cut off because it had writing on it. The zippers on the hems work fine. Made of 100% polyester. They will be folded compactly and shipped via Yu-Packet Post Mini. As this is an anonymous shipping method, returns and refunds are not accepted.
