Our Fabrics
Where Everything Begins
At The Sleep Shirt, fabric is the foundation.
Sleepwear rests against the skin for hours at a time, night after night. It is washed more than almost anything else in a wardrobe. It must breathe. It must endure. It must feel beautiful - even after hundreds of wears.
We work exclusively with natural fibres, primarily 100% cotton and 100% linen, sourced from respected mills in regions known for fine shirting and natural fibre weaving. Many of our fabrics are OEKO-TEX® certified, and we prioritize responsible initiatives such as Better Cotton (BCI) and, when available, GOTS-certified organic cotton.
No synthetics. No shortcuts. Just natural fabrics chosen with intention.
Cotton: The Art of Shirting, Reimagined
Our cottons are elevated shirting fabrics, the kind traditionally reserved for beautifully tailored garments, thoughtfully adapted for sleep.
Within our collection, you’ll find:
-
Smooth shirtings that feel refined and polished against the skin
-
Oxford cloths with gentle texture and structure that soften beautifully with washing and time
-
Lightweight voiles that feel airy, delicate, and breathable
We prioritize long-staple cottons for strength and softness, ensuring durability through frequent washing. Over time, these fabrics relax and become even more comfortable, developing character without losing integrity.
This is why we believe cotton remains one of the best fabrics to sleep in: breathable, natural, and made to live in.
Linen: Naturally Beautiful, Endlessly Refined
Our linens are woven from European flax and finished by skilled mills known for their craftsmanship.
Linen is one of the oldest textile fibres in the world, valued not only for its breathability and strength, but for its unmistakable beauty. There is something inherently sophisticated about linen: the subtle texture, the gentle movement, the way it catches light.
It is relaxed yet refined. Understated yet luxurious.
We choose linen for its:
-
Natural airflow and cooling properties
-
Strength and longevity
-
Sustainable cultivation
-
Softening character over time
-
Effortless, lived-in elegance
It wrinkles. It breathes. It evolves.
Few natural fabrics for sleeping feel as honest and beautiful as linen.

Flannel: Soft Warmth, Elevated
Our flannels begin as high-quality cotton and are brushed for softness and warmth. The brushing process creates a gentle loft, offering comfort without heaviness while maintaining breathability.
Some of our flannels are blended with a small percentage of cashmere, adding an additional layer of softness and refinement. The result is warmth that feels light, never bulky — comforting from the first wear and even softer with time.
Natural, breathable, and enduring, our flannels are designed for cooler months without sacrificing elegance.
Why Fabric Matters
We believe what you sleep in deserves as much consideration as what you wear during the day.
Sleepwear is washed repeatedly. It moves with you and lives close to the body. When made well from high-quality natural fibres, its cost per wear becomes remarkably low.
Many of our customers have worn their Sleep Shirts for years through countless washes, because the integrity of the fabric holds.
We choose fabrics not only for how it looks, but for how it feels on the skin, how it drapes on the body, and how it evolves over time.
Quality reveals itself slowly.
