All of our zipper are made by YKK in India. YKK is a global leader when it comes to zipper production and they are also a leader in terms of eco and ethical responsibility. They are transparent about their sustainable management practices and third party audits of all their factories are performed annually. They meet our ethically made guidelines and all dyes used are considered low impact. Currently, we use their brass zippers with polyester tape. Our zippers are made at the TKK factory in Coimbatore which is about 60 miles west of our garment production company - Five P Venture.
