Our Fabrics
Natural Fibres. Enduring Cloth.
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 years of wear.
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 when available, we prioritize Better Cotton Initiative (BCI) and GOTS-certified options.
No synthetics. No shortcuts. Just natural fabrics chosen with intention.
Cotton: Elevated Everyday Ease
Our cotton sleepwear is made from refined shirting fabrics traditionally reserved for tailored garments, reimagined for rest.
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 durability, ensuring each garment withstands frequent washing while becoming softer with wear.
Cotton remains one of the best fabrics to sleep in — breathable, natural, and enduring
Linen: Natural Texture, Understated Sophistication
Our linen sleepwear is woven from European flax and valued for its breathability, strength, and distinctive texture.
Linen is one of the most environmentally responsible natural fibres available. Flax requires significantly less water than conventional cotton, thrives with minimal irrigation, and utilizes nearly every part of the plant. It is biodegradable, durable, and inherently long-lasting; making it as sustainable as it is beautiful.
Linen regulates temperature naturally, making it ideal for warm climates and layered living. It begins with gentle structure and evolves into softness with time.
There is a quiet confidence to linen in the way it moves and catches light, the way it develops character with wear.
Few natural fabrics for sleeping feel as honest, refined, and enduring.
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, and comforting from the first wear.
Breathable and long lasting, 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 lives close to the body and becomes part of daily ritual. When made from high-quality natural fibres, it is worn and washed again and again, growing softer while maintaining its integrity. We choose fabric not only for how it looks, but for how it feels in the hand and how it evolves with time.
Quality reveals itself slowly.
