We offer several collections, with different fibers and/or focus to fit your style and values, but they all share key characteristics.

We use the finest, luxury fibers that Nature provides and humans / machines shape into yarn and eventually finished garments.

We can trace most of the fibers back to the ranch of origin.

We make garments only with one type of fiber to allow recyclability down the road.

Climate Beneficial Fine Merino Wool from the American West

We source all our US grown merino wool from the Climate Beneficial Verified Wool (CBW) that is traceable back to the ranch of origin.

The fiber is responsibly grown and ethically harvested by ranchers in the rolling hills of California, who steward their flocks and make the best use of their agricultural resources through mindful carbon-farm planning and implementation designed to move the ranch to having a climate beneficial, net-negative greenhouse gas operation.

Raw fiber is spun into yarn in a mill in North Carolina.

We love the Natural, snowy, off-white yarn which has no dyes whatsoever and strongly encourage you to embrace the raw beauty of it.

For customers who want more pigmentation in their lives, we offer a few dyed yarns processed by a state-of-the-art dyehouse in NC, with reduced levels of effluents and carbon footprint, and uses only Azo-free dyes. It is still however a conventional way of dyeing. There are currently no dye houses in the US that use natural dyes AND can dye yarn. Today there is a nascent ecosystem of natural dyes but at the finished garment level, which would force to produce inventory in advance and would negate the benefits of on-demand production)

    

Softest undyed baby alpaca from the high Andes

We source our baby alpaca from a century-old company in Peru focused on animal welfare and healthy land management practices. We can get full traceability of each alpaca lot down to the farm level.

Alpacas graze extensively rather than intensively in high altitude moorlands, and they have soft hooves. Those two characteristics assure that the alpaca luxury fiber is way more regenerative than cashmere, which is leading to massive overgrazing and deforestation.

Alpaca is one of the few natural fibers that has natural color variations. While most animals have light beige hair, some brown and grey hair which allows to create darker garments while still being 100% biodegradable.

Baby alpaca is incredibly soft which makes it a favorite for accessories such as hats and scarfs. It doesn’t however retain shape as well as wool, so using it in garments other than outer draping layers like ponchos can be challenging. For now we are sticking with our principle of using only mono-fibers in order to ensure recyclability, but we may explore wool blends if we can find satisfying mechanical ways of separating them down the road.

     

Finest Andean Merino Naturally Dyed with Herbs in Italy

Chemical conventional dyeing has a huge impact on the health of our planet and the people producing clothes in the current globalized fashion industry. Even the more forward-thinking brands use dyes on supposedly “green” materials.

By using undyed and naturally dyed yarns, SIRKL is able to create a truly biodegradable product that is absolutely harmless to us and our planet.

The only company doing such natural dyeing at the yarn level is to be found in Northern Italy’s tradition of textile luxury craftmanship. Our supplier has developed over many decades a unique process by which yarns of machine-knitting quality are dyed with more than 200 herbs, flowers, roots, bark – with no chemical dyeing processes. No chemicals, no additives, no dye powders, no extracts – no compromises. The natural coloration technology guarantees steadfastness and is the first approved by Woolmark.

The merino extra fine wool is sourced from the high Andes – mostly Uruguay and Argentina, and is traceable down to the farm level. It follows the Nativa protocol, which certifies animal welfare and traceability.

We also offer a limited summer collection with organic cotton and linen, with less color options but still using the same 100% natural dyeing process.

Collections Scorecard: What matters most to you?

We are thriving to be as Radically Good as possible, but are limited for now by the availability of fibers, processes and lack of scale for Good Fashion. We dream of a future in which we can source locally and apply natural dyes locally – but this world does not exist any more, and yet, so we have to make a few concessions along the way.

In the meantime, we have broken down how our collections alongside the key criteria to making a product as harmless as possible to our planet and its people. You can see in the scorecard below how they compare and fit your values best.
