No size tag, but I believe this is a Men’s Large. This jacket is reversible and has pockets on both sides. A perfect jacket for in between and has lots of style. Basically new, I have washed it one time and it has no signs of wear. A great jacket The 100% yarn-dyed flannel face blocks cold wind and has a Deluge® DWR (durable water repellent) finish to shed moisture and spills. The fabric reverses to a 100% all-recycled polyester plain weave in solid colors. A lightweight, compressible layer of 60-g Thermogreen® insulation between the two fabrics adds extra warmth. Finer points include two handwarmer pockets, two chest pockets (one on the solid side) and adjustable cuffs.
