On the lookout for ethical pyjamas or sustainable loungewear? I’ve got you covered, with my big guide to eco-friendly sleepwear for men and women.

When it comes to eco-friendly pyjamas, the most sustainable sleepwear option would be to don an old t-shirt and an old pair of leggings. However, sometimes you want to feel a bit more pulled together. Especially so in autumn and winter when you spend a bit more time in them!

Normally I would advise shopping second-hand for clothing as the most ethical choice. However, I don’t know about you, but pyjamas are one of those things I’d rather buy new than secondhand. 

Instead, I thought I’d look into what ethical pyjamas are out there for men and women. To save you time, I’ve scoured the internet for the best ethical pyjamas, sleepwear, and loungewear for 2023 available to UK shoppers and rounded it up for you below.

Guide to Ethical Pyjamas, Sleepwear and Loungewear

Like many aspects of ethical clothing, choices for ethical sleepwear can be limited. Particularly in terms of size inclusivity and budget. 

That being said, I have come across some great finds. Here are all of the lovely ethical pyjamas that I came across. I’ve additionally added the size range each brand offers, as well as a rough guide to the price per item, to make this guide as helpful as possible. 

I keep this blog post up-to-date (it was last updated in May 2023), so do check back the next time you are in the market for new pyjamas. Hopefully, by then I’ll have more updates and more brands offering more inclusive sizing.

The price range key for this guide is £ = Under £50 | ££ = £50 – 100 | £££ = £100+ for separates.

Cates For: Women (Sizes XS – XL)

Haus of Niya makes stunning hand-printed organic cotton pyjamas for women in a variety of styles – long, short, and cami sets – that are made sustainably from natural dyes and 100% Global Organic Textile Standard (GOTS) certified cotton.

Its range of bright and zingy block-printed patterns are a total joy. And with the luxurious feel of high-end pyjamas, these offer unbeatable value.

What’s to especially love about Haus of Niya is that it operates a zero-waste policy. All of its designs are cut in such a way as to keep textile waste to an absolute minimum. Any leftover material is then used to make matching hair scrunchies.

From pyjama trouser sets to pyjama shorts sets to cami pyjama sets for summer, you’ll find everything for your ethical sleepwear needs.

Linen is a great sustainable fabric choice because every part of the flax plant can be used. What’s more, flax is a rotational crop, farmed naturally in small batches, so it contributes to good soil health. Piglet’s pyjamas ship plastic-free too for that extra feel-good factor.
