Sleep Your Way to Better Recovery
Rather marvellous news for anyone who's ever woken up feeling rather worse for wear: this isn't your average pyjama top. We've rather cleverly engineered a piece of sleepwear that actually works while you're blissfully unconscious, using infrared technology to help your body recover and recharge overnight. Rather good, that.
Why Choose Our Recovery Sleepwear Top
Increased Blood Circulation and Oxygenation: Our infrared fabric technology boosts tissue oxygenation by up to 20 percent and enhances local blood circulation, so you're not just sleeping, you're actively recovering.
Temperature Regulation That Actually Works: The fabric stores thermal energy 63 percent longer than standard materials and dries 65 percent faster, keeping you comfortably warm or cool throughout the night. SPF35 plus rating included, rather sensibly.
Pain Relief and Faster Recovery: Experience an average 25 percent reduction in pain naturally, with accelerated recovery from workouts, injury, and surgery. The technology also reduces inflammation and prevents soft tissue injuries through muscle priming.
Beautifully Made Comfort: Crafted from a blend of Celliant polyester, Tencel lyocell from renewable sources, and spandex, this top feels wonderfully soft against your skin whilst being breathable enough for proper sleep. Drop shoulders and a crew neckline mean you can actually move about without feeling constricted like a rather anxious sausage.
Antimicrobial Protection: Your sleepwear stays fresher longer, which frankly seems only polite.
Product Details
Fabric Composition: 48 percent Celliant polyester, 36 percent Tencel lyocell (compostable and biodegradable), 16 percent spandex
Sizing: Available in XS through XXL. Our model wearing size Large stands at 188 centimetres. Note that our infrared technology works whether the garment is snug or loose, so do choose based on your personal comfort preference. If you fancy a roomier fit, size up from the guide.
Care Instructions: Wash at 30 degrees Celsius, air dry only, no bleach, no dry cleaning. Straightforward, really.
Best Used: Wear overnight after exercise for optimum recovery benefits, or simply to enhance your sleep quality and wake up properly recharged rather than feeling like you've been hit by a bus.
This is rather proper sleepwear engineering. The sort of thing you'll wish you'd discovered ages ago.
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!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.

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.
