Stay Warm, Move Better, Recover Faster
Right, so here's the thing about these leggings: they're rather more than just something to wear to the gym. We've woven infrared technology directly into the fabric itself, which means your body gets to work smarter, not just harder. Think of them as a gentle performance boost that actually sticks around, unlike most promises made on a Monday morning.
Why Choose Our Women's Infrared Performance 3/4 Leggings
Thermoregulating Fabric That Actually Works: Our KYnergy Infrared material retains heat 63 percent longer than standard base layers, and dries 65 percent faster when things get sweaty. Perfect for winter training or outdoor adventures when the weather can't quite make up its mind.
Flatlock Seams for Real Comfort: No rubbing, no chafing, no distracting niggles when you're trying to focus on your workout. The stitching sits flush against your skin, which is rather the opposite of annoying.
Enhanced Circulation and Oxygen: The infrared technology increases tissue oxygenation by up to 20 percent and boosts local blood circulation. Your muscles get more of what they need, which means better performance and speedier recovery.
Naturally Better Recovery: Experience an average 25 percent reduction in pain, accelerated recovery from physical exertion, and up to 80 percent fewer soft tissue injuries through muscle priming. The fabric even reduces inflammation naturally.
Designed to Pair Perfectly: These leggings fit just below the knee, making them ideal companions for infrared compression socks. Together, they eliminate pressure points and bare skin gaps, which is rather splendid for winter sports.
Flexible, Secure Fit: The elasticated waistband is genuinely comfortable, offering both security and flexibility without digging into your midsection during the longest or most demanding workouts.
FDA Certified Medical Device: This isn't marketing fluff. The infrared minerals are embedded within the fabric fibres themselves, so the benefits never wear off. The technology is continually effective and certified as a Class I medical device.

When and How to Use Them
For the best results, wear these leggings throughout your full training cycle: 30 minutes before exercise to prime your muscles and boost circulation, during training and competition, for at least one hour afterwards to support recovery, and as much as possible if you're rehabilitating an injury. The infrared benefits work continuously and are safe for everyday wear.
These leggings have earned their place in the gym bag and on the trail. Quite the showstopper for anyone serious about their performance and recovery.

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.
