sustainable and ethical knitwear production

From our materials through to our design and production processes, Jack Masters is fully committed to making knitwear that does not impact negatively on the environment or people who make it.

Our UK based factory is SEDEX approved. All processes and practices are 100% SEDEX compliant, ensuring you are dealing with an ethical and honourable company.

We are extremely proud of our family-owned and operated factory, the people that work in it and the beautiful garments that we produce - and we want to share the whole story with you. We welcome visitors, so please come and see what we do and how we do it.

Our Commitment

We are committed to a zero waste production process.

Our packaging is all recycled, recyclable or biodegradable.

Our factory is working towards being carbon neutral.

We pay all our workers at least the national minimum wage.


Jack Masters is proud of its status as a business that operates responsibly and sustainably, protects its workers and sources ethically. We strive to provide full transparency to our customers – from yarn to shipping and everything in between.

We try to keep our environmental impact to a minimum by designing, manufacturing, and shipping all from our small, family-owned factory in the heart of England.

Our 3D seam-free knitting process and individual examination of each and every garment means that we achieve a high standard of faultless knitwear and keep waste to a minimum. Where waste cannot be avoided, we ensure that everything that can be recycled, is.

We aim to constantly adapt and improve our sustainable company practices and products.
