I purchased this new at a store this January. The sizes are M and L. They are being sold as a set. Please note that I have selected M in the category selection. The waist cord allowed for considerable size adjustment. I used these for 1 to 2 hours because it was cold outside. (Not for outdoor activities like mountains or the sea.) I am selling them because I no longer need them. I plan to compress them as much as possible for shipping. I haven't used the included pouch, but I may put them in it for shipping. Lightweight and warm down pants, perfect for the outdoors. Workman Repair Tech Washable Fusion Pants - Color: Beige Thank you for looking.
