Stay Warm, Recover Faster, Look Rather Good Doing It
This isn't just another hoodie we've rather hastily thrown together. It's a properly handsome piece of kit engineered with infrared-emitting fabric that actually does something useful, which is refreshingly rare in the world of casual wear. Think of it as a gym companion that works as hard as you do, whether you're lifting weights, jogging in the cold, or simply pretending to look athletic on a morning run.
Why Choose Our Men's Infrared Hoodie
Infrared Technology That Works: Our KYnergy fabric emits infrared heat that helps regulate your body temperature, boost blood circulation by up to 20 percent, and enhance tissue oxygenation. The minerals are woven into the fibres themselves, so the benefits don't fade with washing. It's rather clever, actually.
Brushed Inner Fleece: Luxuriously soft against the skin, this water-repellent fleece keeps you warm and dry without the bulk. It's the sort of comfort you'll want to wear all day.
Active Fit Design: A tapered silhouette with fitted cuffs and sleeves that insulate against cold and wind without restricting movement. The large front pocket is splendid for keeping your hands warm or, you know, your phone.
Recovery and Performance: Wear it 30 minutes before training to prime your muscles and prevent injury. During your workout. For at least an hour after to support recovery. The results speak for themselves with users reporting 25 percent average reduction in muscle soreness and 80 percent fewer soft tissue injuries.
Science-Backed Benefits: FDA certified as a Class I medical device. Increased cellular metabolism, enhanced energy production, reduced inflammation, accelerated recovery from exertion and injury, and SPF35 plus sun protection. Temperature regulation that keeps thermal energy 63 percent longer than standard fabrics when used as a base layer.

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!

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.
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.
