Modal is a regenerated cellulose fibre typically made from beech wood pulp. It is soft, smooth and resistant to shrinkage, making it popular for knitwear and next-to-skin garments.

Founded in Britain in 1970, Jigsaw combines contemporary design with an emphasis on craftsmanship and quality fabrics. The brand works with its own atelier and produces many collections in limited runs, with a focus on distinctive pieces rather than high-volume fashion. Jigsaw also has a longstanding connection with British arts and culture through its Art Foundation.
