Introducing: Wool denim
A fresh take on lifestyle
Denim carries stories – of work, rebellion, everyday life. It is one of the most recognisable fabrics in the world, shaped by history and worn by millions. For this project, we have taken everything people love about denim and enhanced its familiar cotton face with our beloved Merino wool.
The result is a fabric that stays true to the authentic denim look while feeling softer, more breathable, and thus fitting perfectly into all the moments of your day.
Design concept and inspiration
The vision of this project was to preserve the unmistakable character of denim while elevating it with the softness, drape and natural thermoregulation of Merino wool. The ambition was clear:
- Keep the authentic indigo look that defines denim.
- Add the softness and breathability of Merino, making it comfortable to wear in diverse climates.
- Ensure practicality through easy-care properties, so garments can be machine washed and tumble dried without compromising in quality.
Compared to conventional denim, this fabric feels softer and smoother on the skin while keeping the casual look that makes denim so versatile. It’s relaxed, refined, and made for everyday wear.




Three weights, endless versatility
Maintaining the authentic denim look was essential. To achieve this, our partner Berto Industria Tessile selected special cotton warp yarns with the characteristic irregular texture of denim and dyed them with indigo. All three fabric variations were constructed using a 3/1 twill weave, the classic denim structure. By adjusting yarn density, the team created three distinct weights:
- Lightweight: more fluid, ideal for shirts and dresses.
- Mid-weight: versatile, suitable for a wide range of garments.
- Heavyweight: robust, perfect for trousers and structured jackets.
This range gives designers freedom to move between categories while keeping a unified look and feel. The fabric’s non-stretch nature makes relaxed fits the ideal choice.
How the project came together
Designed for impact, built for wearability
Development process and technical challenges
The key technical challenge was to align an indigo-dyed cotton warp with a 100% Merino wool TEC weft: two very different fibres with distinct behaviours in weaving and finishing. Getting the right balance of stability, durability, and a consistent look required several rounds of refinement.
The team experimented with yarn counts, loom settings and finishing techniques to find the perfect balance between structure and softness. The easy-care treatment on the wool was pivotal, ensuring the fabric retained its shape and touch after domestic wash and drying cycles. Finishing was carefully engineered to preserve the indigo vibrancy while allowing the Merino weft to express its natural softness.
Shaping what’s next
Yarn selection and quality testing
The Merino weft was carefully chosen for its smooth hand, fluid drape and compatibility with easy-care maintenance. Alternative wool options were considered less suitable due to potential compromises in comfort or weaving stability, and blended routes risked reducing the signature softness and breathability associated with Merino.

Regular standard quality checks were performed to ensure durability and performance:
- Dimensional stability
- Washing tests
- Rubbing
- Lightfastness
- Acid and basic sweat resistance
Results and future outlook
The outcome is a versatile denim fabric that feels familiar yet new: authentic in look, but softer and more luxurious to the touch. It brings Merino’s natural thermoregulation for comfort in every season, along with easy-care functionality that supports both machine washing and tumble drying.
Looking ahead, the team sees potential in introducing stretch versions and new finishes, expanding how denim can look, feel, and move in the future.
