Since 1850, spinning trends.
Every Eternal Overflow piece begins long before the first stitch, in the hills of Borgosesia, Italy, where Zegna Baruffa has spun the finest merino wool in the world for over 170 years.
Their Cashwool® is not ordinary merino. It's an extrafine wool, selected for its exceptional softness, breathability, and resilience.
Fiber so fine it rivals cashmere, yet built to outlast it.

We chose Zegna Baruffa not because it's expected of premium knitwear, but because nothing else came close. The way it holds its shape after a hundred wears. The way it breathes in warm rooms and insulates in cold ones. The way it feels against skin — not just soft, but alive.
This is not fast fashion's idea of wool. It's a material with a history, a craft passed down through generations of Italian spinners who understood something simple: that quality cannot be rushed.
