This is a base layer set made of a wool, silk, and polyester blend. I purchased it last year and tried it on after opening the package, but it didn't fit, so I'm selling it. The size is marked as XL, but it runs small. Please check the measurements below. It's new, only tried on. Shirt Front length: approx. 54 cm Width: approx. 42 cm Sleeve length: approx. 57 cm Pants Total length: approx. 94 cm Inseam: approx. 64 cm Waist (flat): approx. 30-43 cm Thank you.
