SIRPLUS was founded on the belief that waste is, quite simply, too wasteful. 

A lot has happened since Henry Hales first found a shirtmaker’s offcuts. It’s been over 10 years since then, but some things don’t change.

SIRPLUS started with surplus. And as we’ve grown, we have always returned to our purpose. We still see waste as an opportunity. The opportunity to turn specially selected offcuts into lifetime companion pieces, for a life well-lived. 


Our Fabrics

As our line has grown, we have adopted more fabrics into the fray. Wherever we can, we source fabrics that fit with our principles - to create clothing that looks good and does good too.  

Approximately half of our garments are still made using surplus. 

When it isn’t possible to source the right kind of surplus, we commission carefully selected non-surplus materials. Organic cotton. British-spun wool. Recycled cashmere. Always ethically produced and held to the same high standards we demand of our surplus pieces, meaning every piece is durable and hard-wearing. 

Here’s a breakdown of what we use and why we use it.


We may have come a long way from rifling through shirtmaker’s supplicants, but we still use surplus wherever we can. Now, with a larger team, we scour the world for the highest quality -Italian designer brands, high-end fashion houses and one-off finds. All from“dead stock” - offcuts and unwanted fabrics which would otherwise go to landfill. Our boxer shorts, our jackets, and our waist coats still make heavy use of these repurposed fabrics. 

Our Limited Edition pieces are made from our pick of really special surplus fabrics. We might just have a couple of meters or enough for 20 jackets. So when they’re gone, they are really gone. 

Most of our Cotton and Silk Boxers, Dressing Gowns and Outerwear are made from some fine surplus fabrics too.

Recycled Polyester

Created from discarded plastic bottles, recycled polyester is a wonder. It can be blended with soft wool in a crew neck jumper for lightweight warmth.  

Recycled polyester can mimic wool to create a pile effect teddy, that’s both fast drying and insulating. 

Fashioned into outerwear, it can be an ideal waterproof that keeps out the cold and wet winters. 

Used as a microfibre down in our padded gilet, recycled polyester retains the warmth and breathability of feathers, without any harm to animals or the possibility of allergens.


Agriculturally, linen requires less water than cotton and doesn’t require as many pesticides. 

As it’s derived from the flax plant, it's also biodegradable material. 

We use linen in much of our shirting, it also makes for ideal summer formalwear.


There are 3 types of cotton we strive to work with most. 

Expanding our range came with the increase in our use of organic cotton.

·     Organic cotton aims to minimise the environmental impact of cotton production by trying to remove harmful pesticides and other chemicals from the production process, whilst remaining a wonderfully light and breathable fabric. That’s why we choose it for our t-shirts.

·     The Better Cotton Initiative is helping farmers to grow cotton in a way that reduces stress on the local environment and improves the livelihoods and welfare of farming communities, BCI aims to create long-term change.

·     Recycled cotton, a mixture of post-industrial and post-consumer cotton waste, which we use in our summer shirting.


Our cashmere range is sourced from M.Oro Cashmere. They work on 8,000 acres of organic farms in Ordos, InnerMongolia, and follow organic farming regulations of the United States and theEuropean Union. They take a traditional and natural approach to the care and maintenance of their cashmere goats. They hold a CU organic cashmere certification and has become the world's first and only organic cashmere farm. 

They comply with:

·     ARCHE Advisors - which offers expertise in social auditing, supply chain labour and human rights management.

·     The SFA: Sustainable Fibre Alliance -encourages the adoption of responsible production practices that minimise environmental impact, safeguard herder lifestyles and meet high animal welfare standards.

·     The Responsible Wool Standard -certification ensuring that wool comes from farms which manage their land well, and from sheep that have been treated responsibly.

Our scarves are made using recycled cashmere.


Buttons, our delightful obsession. 

We’ve eliminated all plastic buttons across our shirting (and are almost there with the rest of the range). Instead, we use a few nifty substitutes: coconut, corozo nut, ethically sourced horn& Codelite®.

·     Corozo nuts come from the Tagua tree. These grow in the lowland rainforests of Ecuador, Peru,Columbia and Panama. Corozo is also called “vegetable ivory” because of its similarity to real ivory, which discourages elephant poaching too. 

·     Codelite® buttons are a creamy, shiny material made from milk proteins, with zero-waste produced as a result.
