Women's Infrared Onyx Cycle Jersey:
The Onyx Cycle Jersey boasts a women's cut, hybrid race fit with comfort grip arms and an inverted aero zip, all of which combine to help you cut through the wind whilst ensuring you remain comfortable. The fabric is rated to SPF 35, making the jersey suitable for even the sunniest of days. The three rear pockets provide all the space you need for storing ride essentials and nutrition.
The jersey is made from our infrared-emitting fabric ensuring a breathable and quick drying jersey that retains all the benefits of our KYnergy technology. The infrared technology helps regulate your body temperature, dissipating heat and evaporating sweat better than normal fabrics. Furthermore, this unique technology increases blood circulation, tissue oxygenation and cellular metabolism, meaning your body has more energy available to utilise on the bike.
The KYnergy technology in the fabric also boosts the recovery of muscles all though your body, due to the way the increased oxygenation and circulation of the blood it promotes speeds lactic acid breakdown and reduces inflammation.
KYMIRA Sport products offer their best results when they are utilised across the full sport and training cycle:
Prepare | Perform | Recover | Rehabilitate
For the best results, our products should be used for every phase of exercise:
The effects of the infrared within KYMIRA Sport products won’t diminish over time as the minerals are within the clothing fibres themselves. The infrared is continually beneficial, does not wear off with use, and the products are safe to use continually - certified by the FDA as a class I medical device.

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!
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.

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.
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.
Sostter partners with independent brands that intrigue, inspire, and bring something genuinely different to the world of fashion, design, and living.Join us!
