This is the definitive destination to experience our Cupro Pajamas. This is not sleepwear. This is a uniform for the art of intentional rest, engineered from a brutal, honest principle: in a world that glorifies relentless productivity, the most luxurious act is to consciously and elegantly disengage.
A Synthesis of Innovation and Tradition
The modern world demands a synthesis of the old and the new. Our pajamas are a testament to this philosophy. The material is Cupro, an innovative, sustainable fabric regenerated from cotton waste, known for its silk-like drape and exceptional breathability.
The craftsmanship, however, is timeless. They are ethically crafted by artisans in a family-owned Italian workshop, a place where generations have honed the art of the perfect seam and the elegant silhouette. This is the HACOY synthesis in its purest form: future-forward materials forged by time-honored tradition.
Emotional Durability for Your Most Private Moments
We reject the premise of disposable loungewear. The garments you wear in your most quiet, restorative moments should be crafted with the highest level of integrity and care. This is "Comfortable Elegance" as a foundation for wellbeing.
These pieces are designed for emotional durability, to become a trusted part of your evening ritual for years to come. The feeling is one of "Quiet Luxury"—not the luxury of showing off, but the profound, private luxury of being perfectly, comfortably, and sustainably at peace.
Explore the collection and discover a more intentional, elegant, and restorative approach to rest. This is not about sleeping better. It is about living better.

Care Instructions
Care Instructions
Cupro loves water and is wonderfully easy to live with. Machine wash cool at 30°C on a gentle cycle with a mild detergent.
Reshape the garment while it is still damp, then hang or lay it flat to air dry. Keep it away from direct sunlight and high heat, which can fade or shrink the fabric.
To bring back the signature silky sheen, iron on low heat or simply steam. Please do not tumble dry. Cared for this way, your cupro pajamas will stay soft, fluid and beautiful for years to come.

Why We Made This (Key Highlights)
The Vegan Silk: Made from 100% Cupro, a regenerated cellulose fabric that feels like silk but breathes like cotton.
Italian Tailoring: This is not standard sleepwear. It is tailored in Ferrara with the same precision as a suit.
Thermal Regulation: Cupro is naturally cool to the touch and regulates body heat for deep, uninterrupted sleep.
Circular Material: Produced from cotton linter (a byproduct of cotton production) sourced in Spain, making it zero-waste.
Product Details & Craftsmanship
The Architecture
We wanted to create a uniform for the "Art of Rest." Most pajamas are sloppy. Ours are structured. The shirt features a camp collar and mother-of-pearl buttons, allowing it to be worn as a lounge shirt or even out for coffee. The trousers have a relaxed, fluid drape that moves with you during sleep without twisting. This is "Comfortable Elegance" for the 8 hours that matter most.
Technical Specs
- Material: 100% Cupro (Regenerated Cellulose).
- Origin: Handcrafted in Ferrara, Italy.
- Fabric Source: Spain (EU).
- Feel: Cool, silky, fluid (often called "Vegan Silk").
- Sustainability: Closed-loop production process, biodegradable.
What is Cupro?
Cupro is a plant-based fabric made from cotton linter—the tiny fibers that stick to the cotton seed and are usually thrown away. By regenerating this waste, we create a fabric that is hypoallergenic, anti-static, and incredibly sustainable. It has the sheen of silk but is easier to care for.
Care Guide
Cupro loves water. Wash at 30°C on a gentle cycle. Reshape while damp. Hang to air dry. Iron on low heat (or steam) to restore the incredible silky shine. Do not tumble dry.
FAQ
- Does it shrink? Cupro is pre-shrunk, but like all natural fibers, avoid high heat to maintain the fit.
- Can I wear the top outside? Absolutely. The design is inspired by classic resort wear. Pair the top with our Linen Trousers for a summer evening look.
- Is it breathable? Yes, it is more breathable than synthetic satin and regulates moisture better than standard cotton.
