When you're choosing new pyjamas, the fabric makes all the difference to how well you sleep. But with so many names on labels (bamboo, viscose, rayon, cotton), it can be hard to know what you're actually buying. Here's a simple guide.
Bamboo vs rayon: are they different?
This surprises a lot of people: bamboo sleepwear is usually bamboo viscose, which is a type of rayon.
Rayon (also called viscose) is made by taking plant cellulose and turning it into a soft, smooth fibre. The cellulose can come from different plants:
- Wood pulp, such as beech or eucalyptus
- Bamboo, which is where "bamboo viscose" comes from
Whichever plant it starts from, the process is the same and so are the qualities: silky, soft and breathable, with a beautiful drape.
So when you're comparing "bamboo" pyjamas with rayon pyjamas, you're comparing two fabrics made the same way.
What is rayon like to sleep in?
Rayon is one of the most comfortable fabrics for sleepwear:
- Silky-soft, so it's gentle against your skin
- Breathable and lightweight, a great choice for hot sleepers
- Beautifully draped, so it falls softly rather than clinging
- Comfortable year round, cool in summer and cosy under the covers in winter
Our rayon is plant-derived from wood pulp and OEKO-TEX® certified, which means it's tested to be free from harmful substances. You can read more on our Our Fabrics page.
What is cotton like to sleep in?
Cotton is a natural fibre and a long-time favourite for sleepwear:
- Breathable and airy, so it doesn't trap heat
- Soft, with a crisper feel than rayon
- Easy to care for and softens with every wash
- Perfect in summer and comfortable year round
Cotton seersucker, with its gently rippled texture, sits lightly away from your skin. That makes it especially good on warm, humid nights.
Which fabric should you choose?
| If you… | Try |
|---|---|
| Love a silky, flowing feel | Rayon |
| Sleep hot | Rayon or cotton seersucker |
| Prefer a crisper, classic feel | Cotton |
| Want something that softens over time | Cotton |
| Want long PJs that still feel light | Rayon or cotton seersucker |
There's no wrong answer. It really comes down to the feel you love most.

Yes. Rayon is lightweight and breathable, with a cool, silky feel against the skin. That's why it's a favourite with hot sleepers.
Is bamboo sleepwear the same as rayon?
Bamboo sleepwear is usually bamboo viscose, which is a type of rayon. Both are made by turning plant pulp into a soft fibre, so they share the same softness, drape and breathability.
