Women’s Infrared Performance Baselayer Top
Overview
The Women’s Infrared Performance Baselayer Top is engineered for women who want to train stronger, warm up faster, and stay comfortable through every session. Powered by KYMIRA’s clinically supported infrared‑emitting fabric, this top converts your natural body heat into infrared energy—boosting circulation, enhancing oxygenation, and improving cellular energy output to help you perform at your best.
Designed for high‑performance female athletes and active women across running, gym training, outdoor sport, team sport, and year‑round conditioning, this baselayer is the foundation of better warm‑ups, steadier output, smarter temperature control, and faster recovery.
Key Benefits
1. Train Stronger, Perform Longer
Clinically proven infrared technology supports faster oxygen delivery and improved muscle efficiency—helping you push harder without burning out early.
2. High‑Comfort Fit That Moves With You
With a women‑specific athletic cut, flatlock seams, and seam‑free movement zones, this top supports your body through lifting, running, strength work, and dynamic movement—without irritation or restriction.
3. Stay Cool When It’s Hot & Warm When It’s Cold
Breathable, quick‑drying fabric works with infrared‑driven thermoregulation to keep you comfortable in any environment—warm‑up to cool‑down, indoors or outdoors.
4. Continuous Recovery Support
After your workout, the same infrared technology continues working—helping reduce soreness, increase blood flow, and support faster post‑session recovery.
5. Trusted Technology for All Levels of Sport
Safe, natural, and proven—KYMIRA infrared fabrics are used across elite performance environments and approved for use in all levels of competition.
6. The Most Versatile Women’s Baselayer
Perfect for gym training, running, outdoor sessions, cool‑weather layering, sport warm‑ups, recovery phases, and everyday active life.

The Science Inside KYMIRA's Infrared Performance Baselayers
What it is
KYMIRA’s patented KYnergy® infrared textile embeds a matrix of bioceramic minerals into each fibre. These minerals capture body heat and convert it into far‑infrared (FIR) light in the 6–14 µm range, a wavelength shown in clinical literature to penetrate tissue and stimulate beneficial biological responses that support circulation, oxygenation, energy production, and recovery.
How it works (step‑by‑step the headlines)
1. Energy conversion: Body heat → absorbed by mineral matrix → re‑emitted as FIR (6–14 µm).
2. Nitric Oxide Activation → Vasodilation
FIR exposure is linked to increased nitric oxide availability, promoting local vasodilation and improved micro‑circulation.
3. Enhanced Oxygen Delivery (tcPO₂)
Independent tcPO₂ studies show that FIR garments raise tissue oxygenation, supporting aerobic energy pathways at a lower physiological cost.
4. Mitochondrial efficiency: FIR accelerates cellular energy (ATP) production, aiding sustained output and reduced fatigue.
5. Improved Biological Signalling (Adaptation Support): Exercise studies show FIR garments activate signalling pathways related to mitochondrial biogenesis and angiogenesis
6. Thermal Comfort & Temperature Balance
FIR helps stabilise micro‑temperature during and after exercise, while the textile maintains breathability and moisture management.

Why it matters for performance
- Increased Power, Strength & Endurance Capacity
Improved oxygen delivery, faster aerobic system activation, and more efficient ATP energy production, combined with reduced oxygen consumption requirements, support higher sustained intensities and greater total work output, increased average power, stronger muscles, better neuromuscular efficiency, increased explosive power, coordination. In clinical trials by the University of Loughborough, wearing KYMIRA Infrared has been shown to improve athletic performance by up to 8.7% from first wear.
- Better Movement Quality & Soft Tissue Readiness
Enhanced local circulation and oxygenation help prime muscles to be stronger and more flexible, improving mobility, reducing stiffness, and supporting more consistent movement patterns during sessions. Clinical trials show users have better control and stability during high-speed movements, alongside increased jump height and grip strength.
Greater acute skeletal muscle adaptive responses during exercise, with increased mitochondrial and angiogenic signalling. Leading to quicker training adaptions biologically.
- Rapid in-session recovery: The same mechanisms support repair — removing waste products like lactic acid quicker, reducing muscle micro-tears that create DOMS, reducing in-session fatiguing and inflammation marker metabolites, and activating the pain and inflammation modulating pathways, reducing feelings of soreness.
Why KYMIRA Supports Injury Prevention
- Enhanced local circulation and oxygenation help prime muscles to be stronger and more flexible, improving mobility, reducing stiffness, and supporting more consistent movement patterns during sessions. Clinical trials show users have better control and stability during high-speed movements. This prevents the creation of micro muscle tears that contribute to DOMS, and to larger soft-tissue injuries.
- Improved oxygenation supports efficient muscular contraction and reduces fatigue related injury risk.
- Cellular energy support (enhanced energy ATP production), reduced aerobic pathway and oxygen use, greater endurance and reductions in fatiguing metabolites in session, supports stable movement patterns and reduces compensatory mechanics from tiredness.
- Temperature regulation helps prevent cold related tightness and maintains muscle compliance.
- Accelerated recovery mechanisms, reductions in fatiguing metabolites, and reductions in inflammatory markers during and between sessions, reduce cumulative tissue stress experienced in session.
- Increased angiogenic signalling and mitochondrial angiogenesis support quicker training adaptions for safer movements.
