Like a Hug You Can Actually Wear
For days when jeans feel like an act of aggression and pyjamas lack ambition, these fabulously made sustainable sweatpants are the marvellously guilt-free middle ground. They're absurdly comfortable, quietly stylish, and just ethical enough to make you look smug in the most likeable way possible.
Why Choose Our Sustainable Sweatpants for Women?
Eco Friendly Fabric: Made with 55 percent recycled cotton and 45 percent recycled polyester, which sounds impressively responsible because, well, it is.
Certified Conscience: Global Recycled Standard and Oeko Tex 100 approved, so you can feel marvellous about that second cup of coffee on the sofa.
Properly European: Expertly crafted in the EU with considerable charm and none of the usual complications.
Wonderfully Versatile: Perfect for your next yoga class, trip to the shops, or highly convincing impression of productivity on video calls.
Swift Delivery: Arrives on your doorstep faster than your next excuse not to leave the house.
Product Details:
Care Instructions: Wash cold (30 degrees or under), iron on low, no bleach, and air dry if you're feeling virtuous. Treat with the care usually reserved for pets or beloved jumpers.
Fabric Composition: 55 percent recycled cotton, 45 percent recycled polyester.
Origin: Responsibly crafted within the European Union. No drama, just great trousers.
Fit: Relaxed yet refined. Imagine you're ready for yoga or sleep and haven't completely committed to either.
Colour Options: Stylishly understated shades that pair beautifully with... pretty much whatever's clean-ish.
Certifications: Internationally recognised eco approvals. Because your sweatpants should work as hard for the planet as they do for your comfort.
Slip Into Something Slightly More Fabulous
Don’t dawdle. These delightfully stylish sweatpants won’t wait around forever, and frankly, neither should you if comfort with a conscience sounds like your sort of thing.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
