Stay Warm, Move Better, Recover Faster
Right then, let's be honest. Most fleeces are rather... well, just fleeces. This one, however, does rather more than keep you toasty. Our Infrared Half Zip Fleece is engineered to actually help your body work better, whether you're grinding through a gym session, tackling a mountain run, or simply trying to look fabulous while remaining sensible about temperature control.
Why Choose Our Infrared Half Zip Fleece
- Infrared Technology That Actually Works: The fabric emits gentle infrared heat that promotes blood circulation by up to 20 percent increased tissue oxygenation, meaning your muscles get more oxygen and recover faster. Rather clever, really.
- Brushed Inner Fleece: Luxuriously soft against your skin with a water-repellent outer layer that laughs in the face of drizzle and mild downpours.
- Smart Temperature Regulation: Stores thermal energy 63 percent longer than standard fabrics and dries 65 percent faster. Perfect for layering or wearing solo.
- Secure Zip Pockets: Two generously sized pockets with proper zips, so your keys and essentials won't stage a dramatic escape mid-workout.
- High Rise Collar and Wide Zip Lock Neck: Insulates beautifully against cold and wind, and designed wide enough to slip on and off whilst wearing a cycling helmet or ski gear.
- Active Fit Tailoring: Tapered enough to look properly handsome, loose enough to actually move in without feeling imprisoned.
- Natural Pain Relief: Users report an average 25 percent reduction in discomfort, with 80 percent fewer soft tissue injuries thanks to muscle priming benefits.
- Performance Recovery: Wear for at least thirty minutes before exercise, during your session, and for an hour afterwards to optimise those rather marvellous recovery benefits.

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!
PAYMENT

Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay

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.
