Look Rather Good While Your Body Does All the Heavy Lifting
Here's a rather marvellous bit of sportswear that does precisely what it says on the tin. This cap sleeve top pairs a flattering, form-enhancing fit with infrared technology that actually works. Wear it during training, during recovery, or frankly whenever you fancy looking fabulous while your muscles get on with the serious business of performing and recovering. It's the sort of thing that makes you feel rather brilliant about yourself, which is always a bonus.
Why Choose Our Women's Infrared Performance Cap Sleeve Top
Infrared Technology That Actually Boosts Performance Our KYnergy infrared fabric triggers increased nitric oxide production, priming your muscles for better elasticity and reducing injury risk by up to 80 percent on average. You'll notice genuine improvements in endurance, power, strength, flexibility and mobility while experiencing less performance fatigue.
Recovery That Works While You Sleep The beauty of this top is that you needn't look like you're trying. Wear it during the day for everyday life, during your workout, or while you sleep. The infrared accelerates recovery from physical exertion, injury and surgery, while temporarily relieving pain by an average of 25 percent naturally. DOMS becomes less bothersome, and pre-exertion recovery speeds up considerably.
A Fit That's Actually Rather Flattering We've designed this with both comfort and aesthetics in mind. The empire waist, forward side seams and raglan sleeve create a form-enhancing silhouette that's looser than our base layers but still beautifully shaped. Minimal branding means it works with everything in your wardrobe.
All-Day Comfort and Protection The fabric regulates temperature brilliantly, storing thermal energy 63 percent longer than standard fabrics when used as a base layer and drying 65 percent faster than average. You'll also enjoy SPF 35 plus protection and antimicrobial properties, making this rather good for genuine everyday wear.
Product Details
Fit and Design: Slim fit with raglan sleeves, empire waist design and forward side seams for a flattering shape. Slightly looser than our base layers for comfortable all-day wear.
Fabric Composition: 50 percent KYnergy Polyester, 32 percent Polyester, 18 percent Elastane
Size and Fit Guide: Model wearing XS at 5ft 10 inches. Our garments need not be tight against the skin for the infrared technology to function, so size to your personal preference. If you prefer a looser fit, size up from the guide's suggestions. Women's sizing runs XS through XL.
Infrared Benefits Include: Increased local blood circulation, tissue oxygenation up to 20 percent, enhanced cellular metabolism and energy production, temporary pain relief, accelerated recovery from injury and surgery, reduced inflammation, injury prevention through muscle priming, intelligent temperature regulation, SPF 35 plus rating and antimicrobial protection.
Best Used Across Your Full Cycle: Wear 30 minutes before performing to prime your muscles and boost circulation. Wear during training and competitions. Wear for at least one hour afterwards to support recovery. Wear as much as possible if rehabilitating an injury. FDA certified as a Class I medical device. The infrared minerals are built into the fabric itself, so benefits never diminish with time or use.
Care Instructions: Wash at 30 degrees Celsius. Do not tumble dry.
This top represents rather good value for something that genuinely improves both how you look and how your body performs. If you're serious about training smart and recovering properly, this is precisely the sort of piece that earns its place in your rotation.

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.
