At Simswear, we believe that the finest materials are the foundation of great knitwear. When it comes to cashmere and lambswool, there’s one name we trust the most: Todd & Duncan. Regarded as the UK’s - and arguably the world’s - leading yarn spinners, they’ve been setting the gold standard for natural fibre production since 1867 - bringing over 150 years of expertise to every cone of yarn they produce.

Their mill, nestled in a nature reserve on the shores of Loch Leven in Kinross, Scotland, is a testament to tradition and excellence. The soft, pure waters of the loch play a crucial role in refining their yarns, helping to create the unmistakable softness and quality they’re known for. Sourcing the finest nomadic cashmere from Mongolia and merino lambswool from Australia and New Zealand, they select fibres for their superior warmth, durability, and luxurious feel.

What sets Todd & Duncan apart is their unwavering dedication to their craft. Every strand of yarn they produce goes through a meticulous spinning and finishing process to ensure the highest possible quality. Unlike most modern mills, they still use 60-year-old spinning machines - not for nostalgia, but because these machines are gentler on the long-staple fibres, preserving their strength and softness in a way that modern high-speed machines simply can’t.

This attention to detail aligns perfectly with our philosophy at Simswear. Our partnership with Todd & Duncan allows us to create garments that aren’t just luxurious, but built to last a lifetime. Together, we share a commitment to heritage, sustainability, and craftsmanship, ensuring that every Simswear piece reflects the very best of Scottish textile tradition.
