Men’s Infrared Performance T‑Shirt
Overview
The Men’s Infrared Performance & Training T‑Shirt is built for athletes who want more from every session — more speed, more comfort, more energy, and more consistency. Powered by KYMIRA’s clinically supported infrared‑emitting textile technology, this ultra‑light training tee converts your natural body heat into infrared energy that increases circulation, enhances oxygenation, and drives cellular energy production during performance.
Engineered for general training, gym work, outdoor sessions on warm days, and year‑round conditioning, this T‑shirt delivers the perfect blend of high‑tech performance, breathable comfort, and lightweight mobility—making it your go‑to layer for harder sessions, smarter thermoregulation, and faster recovery.
Key Benefits
1. Perform Better, for Longer
Infrared technology naturally boosts circulation and tissue oxygenation, helping you push further with less fatigue.
2. Ultra‑Light Comfort You Can Train Hard In
With a two‑panel construction, lightweight fabric, and a seamless open‑neck design, this T‑shirt reduces friction, improves airflow, and keeps you moving freely during intense gym work or outdoor sessions.
3. Stay Cool When It Heats Up
The breathable, quick‑drying fabric works with infrared‑driven temperature regulation to help manage heat and sweat—ideal for summer training, HIIT, and warm‑weather performance.
4. Train. Play. Recover.
Infrared continues working after your session ends, supporting immediate post‑session recovery—mirroring the effect seen in KYMIRA’s recovery ranges.
5. Safe, Natural, Approved Results
Suitable for athletes at all levels of competitive sport, thanks to KYMIRA’s validated, non‑invasive technology.
6. The Most Versatile Performance Tee
Perfect for gym sessions, conditioning work, outdoor summer training, hiking, travel, and everyday active wear.
Fit & Construction
- Performance‑Focused Design
- Two‑panel athletic cut for freedom of movement
- Seamless, open‑neck design to reduce friction and improve airflow
- Elongated back panel for functional coverage during lifting and dynamic training
Premium Fabric Engineering
- Ultra‑lightweight yet durable for high‑frequency, high‑intensity use
- Breathable, quick‑drying fabric for superior heat and sweat management
- Extra‑durable stitching for long‑term performance
- Triple‑stitched hems for added strength
- Stretch performance knit for unrestricted motion

Use Protocol
Wear at least 30 minutes before training (90 minutes is optimal for priming), keep it on during training, matches, and high‑output sessions, then switch to KYMIRA recovery wear for 1–4 hours after exercise for maximum recovery effect.
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.
