Smartwool’s excellent quality stretch sports material. Lovingly worn but still in great condition. See photos for details. PLEASE NOTE: I have a small, regularly bathed, short hair dog who lightly sheds, and I will do my very best to avoid any hair coming into contact with your item, and to check for any before I ship it out. However, with gently used clothing, there is always a chance that you might find a stray hair or so when it arrives. Smoke-free home.
