Henry Hales made an interesting discovery while plotting to take over the men's underwear market: Savile Row and Jermyn Street shirt makers often ended up with a surplus of fabric that would otherwise go to waste. Enough fabric to make some seriously good boxers. So, SIRPLUS was born.

Over the last ten years, SIRPLUS has grown from a market stall to multiple central London stores. From upcycled boxer shorts to a full range of functional wardrobe staples. All with a constant connection to our roots in surplus fabric. We design with a vision of your clothes lasting longer, being worn more often and adapting to a variety of seasons.
