An essential piece, made to move with you through everyday life.
Caltha is Nathueral’s signature sweatshirt: soft, easy, and designed to be lived in—not just worn. The shape is relaxed yet refined, created to follow your daily rhythm and layer effortlessly within a timeless wardrobe. Dropped shoulders and ribbed trims complete the silhouette.
Made from 100% natural, plant-based fibres—organic cotton, hemp, or other natural blends. Each piece is handmade in my Ligurian studio, one at a time.
Available in two lines: NathueRAW, where the natural fibre takes centre stage in its pure, essential form, and NathuerART, dyed or embellished with botanical colour through slow, respectful techniques.

The name Caltha comes from Caltha palustris—the marsh marigold, a wild plant that blooms in quiet, water-rich places, among moss and streams in Liguria.Simple, yet resilient—often one of the first to return when everything still feels still.
That’s the spirit of this sweatshirt: steady, cocooning, timeless.
Caltha doesn’t change with the seasons. It returns, grows, and quietly evolves.
