I purchased this at Costco about two years ago. I'm putting it up for sale because I've gained weight and it's likely to be too tight. I hope you understand that it has been stored at home (unopened). Warm innerwear, XL size, set of 2, with a soft feel and excellent heat retention. - Product Name: Warm Innerwear - Size: XL - Material: 55% Acrylic, 40% Rayon, 5% Polyurethane - Features: Heat retention, soft feel - Washing Instructions: Machine washable Thank you for viewing. Thank you very much.
