Gloriously Warm Legs for Everyday Adventurers
Let’s face it — persuading a small person to get dressed on a frosty morning is a bit like reasoning with a squirrel. Which is where these snug thermal merino sweatpants come in. Soft as a particularly affable cloud, light enough for layering, and warm enough to reduce complaints to a mere occasional whimper. Perfect for everything from school runs to garden expeditions and imaginative crusades through the living room.
Why Choose Our Kids Thermal Merino Sweatpants?
- Beautifully Crafted Merino Wool: Ethically sourced and mulesing free, this fabric is marvellously warm yet lets the skin breathe with the grace of a well-mannered breeze.
- Layer Friendly: Thin and lovely, offering just enough warmth to slip under overalls or pair with coats without creating a puffball situation.
- Adjustable Waist: Accommodates growth spurts, snack binges, and ambitious playground acrobatics with ease.
- European Quality: Thoughtfully made with high standards and a touch of continental flair. Frankly, your child might look like a young poet lost in a Nordic forest.
Product Details:
- Care Guide: Machine wash on wool or delicate cycle. Absolutely no need to involve dry cleaning drama.
- Reshape While Damp: Do encourage it to retain its splendid shape. A bit of shrinkage may occur, but nothing tragic.
Keep your little explorer feeling cosy, sprightly and gloriously warm this season. Add to cart now before word gets out.
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.
