Gloriously Practical, Endlessly Adventurous
This sunset red softshell onesie is a rather marvellous solution to the age-old conundrum of how to keep a small child both dry and stylish whilst they wade fearlessly into puddles with the zeal of a Victorian explorer. Smart enough for the park, rugged enough for the woods, and snuggly enough to declare war on wind chills.
Why Choose Our Softshell Onesie?
Weatherproof Wizardry: With a waterproof rating of 10000 mm and breathability of 5000 grams per square metre per day, it bravely fends off rain, slush and unexpected springtime snow flurries like a tiny textile superhero.
Flexible Fit: Adjustable waist and hood, with ribbed cuffs and hems, make it accommodating for growth spurts, snack-induced body changes, and general wriggliness. Utterly clever.
Safety with Style: Thoughtful reflective details help your child stay visible on dusky adventures, be it a twilight game of hide-and-seek or a last-minute dash for conkers.
Pockets with Purpose: Zipped compartments for stashing peculiar stones, biscuit halves, and that small stick called Jeremy. Invaluable for the small but terribly busy collector.
Product Details:
Material: Three-layer softshell with waterproof outer shell, thermoactive middle, and a soft fleece inner lining. Sounds complex because it is.
Ideal Temperature Range: Delightfully insulating from minus six to ten degrees Celsius. British springtime, you’ve officially met your match.
Care: Machine washable at 30 degrees inside out. Kindly skip the tumble dryer unless you fancy a miniature boiler suit.
Made Just for You: Each piece is handcrafted to order in Europe to reduce overproduction. Yours is truly one-of-a-kind. Naturally.
Equip your young adventurer for an irresistibly dashing escapade outdoors. Order now for a splendidly prepared season ahead.
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!
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!

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect. Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience.
Every object tells a story, and every purchase supports an independent brand doing things differently. Explore our British makers, discover sustainable brands, browse women-led businesses, find the perfect gift for her, or simply wander through our new arrivals and see what finds you.
This is just the beginning. But enough about us — read all about us, or step inside and see what catches your imagination.
A Curated Marketplace for Independent Ethical Brands
Discover our world of independent brands, conscious design, and purposeful creativity — all in one place.
Sostter is more than a marketplace. We're here to inspire a more thoughtful way to shop — one that celebrates the makers, the dreamers, and the independent brands doing things properly. Every brand on Sostter has been individually vetted for its originality, quality, and values. From sustainable fashion and ethical homeware to handmade jewellery and design-led gifts — all brought together in one considered space. Browse by location, by purpose, or simply wander and see what finds you. Want to sell with us? We'd love to hear from you.
