We are two Irish sisters who established 3Mac in 2025. The derivation of our company name comes from the Irish word mac meaning 'son'.  We started this brand with one simple belief; boys should feel completely comfortable in what they wear and this is at the heart of everything that we do.

Too often, the smallest details are overlooked, so we set out to change that.  We believe that the little details make all the difference.  From soft, durable fabrics to removing neckline labels and using smooth silk care labels, every piece is designed to feel cosy, comfortable yet practical and stylish.

We want to challenge the idea that boys fashion has to be dull and restrictive, and instead create a brand that celebrates style, comfort and colour.  By introducing fresh designs and a broader colour palette in the future, our goal is to give parents and children alike more exciting choices and to redefine what boys clothing can look like.
