Women's Infrared Core 3.0 3/4 Length Leggings:
As with all our core 3.0 range, these ¾ Length Leggings are about blending comfort with performance technology.
The infrared 3/4 length leggings are made of a thick but lightweight KYnergy® Infrared fabric, which boosts the garment’s thermoregulating qualities whilst retaining our unique material’s benefits for performance and recovery. They fit to just below the knee and have been specifically designed to pair with our infrared compression socks. Together, the garments ensure there is only a slight overlap between sock and legging.
For winter sports this is ideal, as the combination ensures there are no pressure points inside your boots, but also that there is no bare skin.
The leggings feature our flatlock stitching ensures you can run free of distracting rubbing or chafes, and the elasticated waistband is secure and flexible to prevent any digging into your midsection – meaning they remain comfortable over the longest or most demanding workout.

The size charts below detail the relevant sizing or points of measurement for all of our products. Our garments do not need to be tight and against the skin for our infrared technology to work, so we suggest fitting to your personal preference. If you are looking for a looser fit, then size up from the guide's suggestions.

CARE INSTRUCTIONS
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

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!
