Weatherproof Whimsy With a Dash of Daring
If your child is the sort who considers every puddle an invitation and every tree a mission, this softshell onesie is their gloriously practical uniform for daily escapades. Fabulously made for the great outdoors, playground diplomacy, and possibly brunch with grandparents (mud optional).
Why Choose Our Softshell Onesie for Children?
Weather-Defying Comfort: Waterproof up to 10000 mm and as breathable as a gossip at teatime (5000 g per square metre per day), it keeps your little explorer dry without the faintest hint of stickiness. Sidekick to every splash and sprinkle.
Marvelously Adjustable: Clever features like an adjustable hood and waist help it fit just right as your child grows with the speed of envy. Ribbed cuffs and legs keep-out drafts while allowing optimal grub-hunting flexibility. Toasty from minus 6 to 10 degrees Celsius.
Delightfully Stylish: With reflective stripes for top-notch twilight visibility and digital prints that whisper mischief with taste, it’s form meeting function for the chronically curious.
Zippered Treasure Pockets: Ideal for storing pinecones, imaginary coins, or the occasional biscuit. Each onesie is lovingly handmade in Estonia, with stitching as stoic as a British butler and just as dependable.

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.
