Outdoor Voices Navy Snap-Up MegaFleece Small (Men?)

This is a snap-up without a hood so I believe it is a men's size small, however it looks a tad small for a men's small so it could be a women's size small -- I'm not sure. Please read carefully: This is very worn. It is VERY PILLED and has some discoloration at the waist band and cuffs. VERY WORN. This older snap-up style is rare to find in navy but it is very used. Style number: RN147908
