The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.

You’ve probably noticed that different fabrics give you different experiences when you sleep, ranging from warm wool in the winter to cooling bamboo in the summers. One fabric that keeps us thermoregulated all year long? Silk!

For soft, smooth, and sustainable pajamas we love, check out these brands using ethical silk or eco-friendly silk-like alternatives—like organic bamboo. Throw a set on as you get ready for bed, slip on a sleep mask, and enjoy a good night’s rest.

Not into silk? Check out our recommendations for other sustainable pajamas. And, if you’re ready to upgrade your bed, too—here are our top-reviewed natural & organic mattresses.

1. The Ethical Silk Company

Ethics | 100 percent Mulberry silk, fair trade working conditions, artisan-made
Best For | Camisole & short sets
Our Pick | Mulberry Silk Camisole & Short Set ($150)
Price Range | $150

The Ethical Silk Company works with a fair trade tailor in Jaipur, India for its high-quality, sustainable sleepwear. Instead of traditional silk, the brand employs cruelty-free practices by only using silk extracted from the cocoon after the moth has left. The patterns on these PJs are created via block printing, which is done by hand one at a time, using low-impact dyes and recycled water. In addition to full sets, you can also find a number of silk slips and separates.

2. Maylyn & Co.

Ethics | Vegan options, cruelty-free, PETA certified, gives back, fair working conditions
Best For | Vegan silk slips & sets

Maylyn & Co. primarily uses plant-based fabrics and responsibly sourced silk to bring comfort and style into your life. PETA-approved, their collection includes a vegan silk option made from organically farmed Lotus plants. Maylyn & Co. only partners with International Labour Organization-certified factories and finishes pieces in their Toronto space. We especially love the slips and sets for a quick transition from day to night. (Or for 24/7 attire… we’re not judging!)

For silk PJs you can sleep soundly in, we love Quince’s washable sets. They’re woven from 100 percent Mulberry silk, with just enough weight to feel truly indulgent. Each pair is dyed without hazardous chemicals in Bluesign®-certified factories that prioritize reducing water, energy, and chemical use. Quince partners with BCI-certified factories in China aimed to improve working conditions throughout the supply chain so everyone is treated ethically and fairly.

Ettitude is a trailblazer when it comes to organic bamboo that’s actually affordable. Their CleanBamboo™ garments are crafted in a nontoxic, closed-loop system where the water is reused up to 100 times before being discarded. These silk-like pajamas are free of harmful chemicals, hypoallergenic, and breathable for even the most sensitive of sleepers—and they’re pretty darn cozy, too.

PJs got you sweating at night? We got you! Nightire’s organic bamboo pajamas feel like silk but are moisture-wicking (and antibacterial) to keep you cool all night long! And they’re thoughtfully designed with large sleeves for rolling around, not to mention the comfortable hems and elastic waist. Nightire’s sets are both vegan and certified organic, wrapped in packaging from recycled materials. Sleep sweat, be gone!

7. Luna and Noon
