Men’s Infrared Performance Leggings
Train harder. Move faster. Deliver on game day.
Our Infrared Performance Leggings combine a movement‑ready fit with KYMIRA’s infrared technology that actively supports your biology while you train. The fabric’s embedded minerals convert body heat into infrared energy that your body can use — increasing local circulation, improving tissue oxygenation and supporting cellular energy production during effort. The result is greater power, endurance, strength, mobility, flexibility, jump height, and explosive power all whilst experiencing better between-burst recovery, and less in-session fatigue. This is shown to lead to greater athletic performance outcomes, clinically proven.
Engineered for performance: a secure, flexible waistband, seamless front‑to‑back gusset and flatlock stitching minimise distraction and chafe. Breathable, quick‑drying materials manage sweat and comfort through intervals, heavy lifts, runs and matches; a discreet zipped back pocket secures small essentials.
New to infrared? Unlike standard “moisture‑wicking” or pure compression pieces, KYMIRA’s infrared fabrics are active: they trigger biological responses linked to blood flow, oxygen delivery and mitochondrial energy — mechanisms tied to performance and recovery in published research that underpins KYMIRA’s technology.
Key Benefits
1. Perform better, for longer: Clinically proven, naturally accelerated biological effects.
2. Comfort you can push in: Performance cut with seamless gusset and flatlock seams for chafe‑free training and matches.
3. Stay focused when it heats up: Breathable, quick‑drying fabric and temperature regulation support from infrared help manage heat and sweat during efforts.
4. Train. Play. Recover: The same infrared technology continues working after you stop, supporting immediate in and post‑session recovery — a principle shared across KYMIRA’s recovery ranges.
5. Safe to use, natural, approved results. Our garments can be worn at all levels of competitive performance.

The Science Inside KYMIRA's Infrared Performance Leggings
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.
