The JB's Chunky 1/2 Zip Jumper is a classic piece with a modern twist. Its classic fit makes it comfortable and versatile, while the chunky waffle knit adds a touch of texture and warmth. The jumper is made from a blend of 40% wool, 40% acrylic, and 20% polyester, making it soft, durable, and perfect for cooler weather. The antique brass 1/2 zip opening adds a touch of vintage style, while the rib cuff and basque finish off the look.
