This is a fabulous piece! With its vibrant, vibtage-inspired exterior and cozy layer of soft mico-flannel on the inside, this retro vest looks as good as it feels. The fill is 100% polyester and the outside fabric is a plush, water resistant cotton. There are also 2 inside pockets and YKK zippers. Female Model in photo is 5"7 125lbs. and wearing a XS (for fit reference) This is a Size Small. It is brand new and has never been worn. I received it as a gift and it has been hanging in my closet (smoke free/pet free home)
