Fabrics

Made in Portugal

Crafted in Portugal by skilled artisans, our tees reflects decades of expertise in texture and technique. Every piece is thoughtfully refined, ensuring the highest standards of quality are met.

Our production is north of Porto, a region steeped in textile heritage and home to some of Europe’s finest mills and factories. For centuries, textile making has been a way of life in Portugal. From its colonial-era prominence as a cotton exporter to its modern-day reputation for unmatched craftsmanship, the industry has evolved with skill and innovation.

Focusing on small batches and extraordinary attention to detail - it’s this dedication that makes Portugal the perfect place for reimagining the timeless tee.

SELECTED FABRICS

Nature's finest fabrics selected with intent. Organic. Sustainable. Enduring. Each fibre chosen not for trend, but for class. For the way it lives, for the way it lasts. Quietly refined, sensorially rich. Made to be felt and favoured.

Discover textured intimacy.

「絲」SILK

Silk is quiet sophistication. A soft gleam of refinement, spun from nature yet near weightless on skin. It caresses rather than covers; fluid, graceful, instinctively elegant. With every thread, it whispers softness, wrapping the body in subtle sensation.

「棉」COTTON

Cotton is composure made tangible. Honest, breathable, enduring. It fuses effortless ease with quiet strength. Woven from the earth, it adapts and supports, always reliable, never imposing. A humble fabric that becomes more familiar, more personal, with time.

CONSCIOUSLY CRAFTED

Ray of Hours is committed to building a slower, more responsible wardrobe. That means working only with trusted partners who meet strict environmental and ethical standards, choosing certified organic and recycled fibres, and creating garments that last beyond seasons.

This isn’t fast fashion. This is permanent style: built to endure, designed to be worn on repeat.

We believe that fewer, better pieces are not only a personal choice - they’re a powerful act. By investing in longevity over novelty, we reduce waste, honour craftsmanship, and contribute to a more thoughtful fashion future.

Responsible Materials

We carefully select certified fabrics that minimise impact while maximising feel and longevity.

All garments use fibres that meet leading international standards:

GOTS – Global Organic Textile Standard
Organic 100 – Content Standard
Oeko-Tex® Standard 100 – free from harmful substances
GRS – Global Recycled Standard

Our signature blend of silk and organic cotton is both sensorial and sustainable - chosen not just for softness, but for durability and low-impact production.

Production with Purpose

We work with a single, highly specialised manufacturer in Portugal, known for combining quality craftsmanship with responsible practices.

From small-batch production to energy-efficient processes, every detail is considered.

Our partner is selected based on strict environmental, social, and governance (ESG) benchmarks - ensuring fair wages, safe working conditions, and a shared commitment to craft.

Against the Cycle

Ray of Hours is built around a permanent collection model: no trends, no sales, no wasteful overproduction.

By offering fewer but better pieces, we extend the lifecycle of every garment - reducing the need for fast replacement and encouraging thoughtful consumption.

Timelessness is our standard. Longevity is our luxury.
