Ride Faster, Recover Better, Feel the Difference
Right, so here's the thing. We've spent rather a lot of time fiddling about with infrared technology to create a cycling jersey that doesn't just look splendid, but actually helps your body perform. This long sleeve number is the sort of garment that makes you wonder why you didn't buy it sooner, especially when you're powering through autumn sprints or grinding through winter's darkest days.
Why Choose Our Infrared Long Sleeve Jersey
Three Season Versatility: Worn solo on mild October and April days, or layered through January's teeth-chattering depths, this jersey keeps your temperature exactly where it needs to be without all that faffing about with bulky clothing.
KYnergy Infrared Fabric: Our rather clever fabric technology increases blood circulation by up to 20 percent tissue oxygenation, boosts cellular metabolism, and keeps you warm 63 percent longer than standard jerseys. It's the sort of thing that sounds made up until you experience it.
Enhanced Performance and Recovery: The infrared benefits don't just happen during your ride. Increased oxygenation accelerates lactic acid breakdown, reduces inflammation, and supports muscle recovery. You'll feel noticeably fresher the next morning, which is rather marvellous when you've got another ride planned.
Injury Prevention: Muscle priming through infrared technology delivers an 80 percent average reduction in soft tissue injuries. Your body stays primed and protected, whether you're tackling intervals or recovering from exertion.
Hybrid Race Fit: Tapered to your body without excess material to catch the wind, this jersey means business. Three ergonomic rear pockets plus a zipped valuables pocket keep your ride essentials and nutrition exactly where you need them.
Sun Protection: SPF 35 rating keeps UV damage at bay on those longer spring and summer rides.
Quick Drying and Breathable: The fabric dries 65 percent quicker than standard jerseys and breathes beautifully, so you stay comfortable whether you're hammering or cruising.
Product Details
Fabric Composition: 50 percent KYnergy Polyester, 32 percent Polyester, 18 percent Elastane
Key Features: Full length inverted aero zip, comfort grip arms, breathable quick drying technology, SPF 35 rated, FDA certified class I medical device
Care Instructions: Wash at 30 degrees Celsius, do not tumble dry. The infrared benefits won't diminish over time as the minerals are woven into the fibres themselves.
How to Use for Best Results: Wear 30 minutes before performance to prime muscles, during training and competition, and for at least one hour afterwards to support recovery. As much as possible if rehabilitating an injury. The infrared technology is continually beneficial and certified safe for continuous use.
This jersey is genuinely rather good. It looks the part, feels properly made, and most importantly, it delivers tangible performance and recovery benefits that you'll notice on every ride. Get your hands on one before the season properly kicks in.

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.
