Women’s Infrared Performance Training T‑Shirt
Overview
The Women’s Infrared Performance Training T‑Shirt is designed for women who train with intent—whether that’s pushing through intervals, chasing strength goals, or performing at your best in sport. Powered by KYMIRA’s clinically supported infrared‑emitting fabric, this lightweight tee transforms your natural body heat into infrared energy that boosts circulation, increases oxygen delivery, and enhances muscle efficiency during every session.
Soft, breathable, and built for movement, this is your go‑to training essential for better warm‑ups, steadier energy, and faster post‑workout recovery.
Key Benefits
1. Train Stronger & Last Longer
KYMIRA’s patented infrared technology enhances circulation and supports oxygen delivery to working muscles—helping you maintain power and reduce fatigue across training, sport, or conditioning work.
2. Lightweight, Breathable & Sweat‑Managing
The moisture‑wicking, quick‑drying performance fabric keeps you cool and comfortable during high‑intensity sessions, outdoor workouts, studio classes, and warm‑weather training.
3. Supports Faster Recovery
Infrared energy continues working after you stop, helping accelerate waste‑product removal and improve muscle recovery—ideal for women balancing consistent training with lifestyle demands.
4. Female‑Focused Fit for Freedom of Movement
Cut to flatter the female form with a smooth, flexible fit that moves effortlessly with you—whether you’re sprinting, lifting, flowing through mobility, or coaching from the sidelines.
5. Everyday Versatility
Perfect for gym sessions, outdoor runs, HIIT, sport training, hiking, cycling, and all‑day active wear.

The Science Inside KYMIRA's Infrared Performance T-shirt
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.
