Feel Rather Marvellous While You Train and Recover
Right then. We've rather accidentally created something rather splendid. This long sleeve base layer isn't just another bit of sportswear that promises the earth and delivers a damp squib. It's engineered with infrared-emitting fabric that genuinely works with your body, not against it, helping regulate temperature and accelerate recovery in ways normal athletic wear simply cannot manage.
Why Choose Our Women's Recovery Base Layer
Infrared Technology That Actually Does Something: The fabric contains minerals woven directly into the fibres themselves, which boost blood circulation by up to 20 percent and increase tissue oxygenation. Rather marvellous, really. This means more oxygen and energy delivery to your muscles when you need it most.
Designed for Your Body, Not a Generic Diagram: Structured shoulder panels provide genuine freedom of movement whether you're deadlifting, rowing, or simply pretending to be more athletic than you actually are. The tapered, form fitting design follows the contours of your frame rather than billowing about like a sail.
Comfort That Doesn't Quit: We've eliminated friction and chafing through flatlock stitching and tapered seams. The breathable, quick drying fabric means you won't spend your recovery looking like a drowned rat. Dries approximately 65 percent faster than standard athletic wear, which is rather good news when you've got places to be.
Recovery Support That Lasts: Wear it for 30 minutes before training to prime your muscles and prevent injury. Wear it during your workout. Wear it for at least an hour afterwards to support proper recovery. The infrared benefits don't diminish with washing or time, so you're investing in something that remains genuinely useful for years.
Protection and Durability: SPF 35 plus rating means you're covered against sun exposure. Antimicrobial properties keep the fabric fresher longer. Triple stitched hems and durable construction ensure this base layer will outlast your enthusiasm for most things.
Product Details
Fabric Composition: 50 percent infrared emitting polyester, 32 percent polyester, 18 percent elastane for stretch and recovery.
What the Science Says: FDA certified as a Class I medical device. Average 25 percent reduction in pain levels. Average 80 percent reduction in soft tissue injuries through muscle priming. Stores thermal energy 63 percent longer than standard fabrics when layered correctly.
Best Used Across Your Full Training Cycle: Prepare for activity by wearing 30 minutes beforehand. Perform during training and competition. Recover by wearing for at least one hour post exercise. Rehabilitate by wearing continuously if nursing an injury. The infrared technology supports all four phases equally well.
Care Instructions: Wash at 30 degrees Celsius. Do not tumble dry. That's rather straightforward, really.
Rather good recovery starts with rather good clothing. This base layer is fabulously made and properly supports your training ambitions, whether you're recovering from exertion, injury, or simply the effort of becoming the person you're meant to be.

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.
