Gloriously Comfy Sweatpants That Just Happen to Help the Planet
You know that feeling when your trousers hug you just right, as if thanking you for choosing them? Well, these are those. Designed for the sort of chap who values comfort, style and not destroying the environment before tea. Fabulously made from recycled materials in Europe, these sweatpants are ideal for everything from couch lounging to the odd ambitious jog. Or at the very least, standing in the kitchen looking thoughtfully sporty.
Why Choose Our Sustainable Sweatpants?
- Sustainable Materials: Crafted from 55 percent recycled cotton and 45 percent recycled polyester, so you’re dressed rather well while doing rather good.
- Certified Quality: Backed by GRS and Oeko Tex Standard 100, meaning they’re chemically unambiguous and full of righteous comfort.
- European Craftsmanship: Beautifully made in the Netherlands, where tulips bloom and sweatpants are taken terribly seriously.
- Low Impact Living: Designed to tread gently on the Earth, even if your Sunday strolls are particularly enthusiastic.
Product Details:
- Care: Machine wash at or below 30 degrees Celsius to keep the fabric suitably serene.
- Ironing: Low temperature, because no one needs crackling joggers in their life.
- Avoid: Bleach and unnecessary drama. Neither age well.
- Eco Tip: Wash only when someone significant gives you a look. You know the one.
Looking properly handsome while helping the planet is now delightfully easy. Add to basket now and slip into something marvellously sustainable before they’re the talk of the weekend farmers’ market.
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.
