Sleep Better, Recover Faster

Rather good news if you've been spending your nights tossing about like a landed fish: this infrared sleepwear top actually works. Designed to enhance your body's natural recovery process whilst you're blissfully unconscious, it's the sort of thing that makes waking up feel less like a punishment.

Why Choose Our Infrared Recovery Top

Increased Blood Circulation: Your body gets the oxygen it needs precisely when it needs it most, boosting recovery by up to 20 percent tissue oxygenation.
Enhanced Sleep Quality: Wake refreshed rather than feeling as though you've wrestled a particularly aggressive duvet all night.
Post-Workout Recovery: Accelerated recovery after physical exertion, injury or surgery means you'll be ready to go again sooner.
Natural Pain Relief: Experience approximately 25 percent average reduction in discomfort without the faff of additional interventions.
Injury Prevention: 80 percent average reductions in soft tissue injuries through muscle priming, which is rather splendid if you ask us.
Temperature Regulation: Intelligently warms and cools to suit your needs. Stores thermal energy 63 percent longer than standard fabrics and dries 65 percent quicker.
Beautifully Crafted Fit: Flattering 5-button henley neckline drapes loosely for comfort without sacrificing style.
Gentle on Skin: Soft jersey fabric that's utterly fetching and kind to even sensitive skin.
Built-In Sun Protection: SPF 35 plus rating because your nightwear needn't leave you vulnerable.
Antimicrobial Properties: Stays fresher longer, which everyone can appreciate.

Product Details

Fabric Composition: 48 percent Celliant polyester, 36 percent Tencel Lyocell (from renewable, biodegradable sources), 16 percent Spandex.

Size and Fit: Model pictured is wearing size small at 160cm or 5 feet 3 inches tall. Our infrared technology works brilliantly without needing the garment tight against your skin, so size to your preference. If you prefer a looser fit, we suggest sizing up.

Care Instructions: Wash at 30 degrees Celsius or 86 degrees Fahrenheit. Do not tumble dry, dry clean, or add bleach. Rather straightforward, really.

Best Used: Wear overnight to maximise recovery benefits and improve sleep quality. Engineered specifically for post-exercise recovery whilst you dream.

This isn't merely sleepwear. It's a rather good investment in waking up feeling properly human. Don't let another night pass without it.

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.

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.

This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
