- Faster post exertion neuromuscular restoration & readiness

Peer‑reviewed athlete research shows that recovering in KYMIRA FIR garments can deliver highly significant neuromuscular recovery improvements at 24–48 h, compared to placebo. Objective markers of readiness to perform again after the prior session, show next athletic
performance is significantly better following recovery in KYMIRA Infrared. Wearers are in a better biological state and have reduced physiological stress in objective measures.

- Reduced feelings of DOMS, soreness and
inflammation.

Peer-reviewed research shows using KYMIRA Infrared
significantly reduces athletes experiences of DOMS, and modulates pain relief and anti-inflammatory pathways, actively reducing both, with natural effects. Passive, non‑powered recovery you can wear immediately after training, during travel, and overnight—no settings, no sessions to book—drives consistent use and better outcomes.

- Increased Circulation, Oxygenation & Quicker soft-tissue RepairThe observed tcPO₂ rise within 30–90 min aligns with the post‑session window when tissues need oxygen for remodelling and waste clearance, supporting reduced next‑day heaviness and smoother movement quality. This acceleration of recovery processes, continues as long sa your wear KYMIRA.

- Acute Skeletal Muscle Adaptive Responses During Recovery

Clinical studies show significantly increased mitochondrial and angiogenic signalling showing increased angiogenesis,
neuromuscular training adaption results.

Most athletes notice less soreness (DOMS) and quicker freshness between sessions when they wear IR50 post‑workout and in the 24–48‑hour window. KYMIRA‑summarised evidence shows improved tissue oxygenation and microcirculation acutely, and significant neuromuscular recovery improvements at 24–48 h in peer‑reviewed work (e.g., mRSI, countermovement‑jump metrics).

The KYMIRA Trial Measures & Outcomes guide on the clinical studies webpage, also notes early wins on HRV ↑ and resting heart rate ↓ within the first week when wear is consistent.

Yes. KYMIRA® garments are classified as performance clothing, not regulated equipment. They contain no electronics, no
sensors, no prohibited materials and are fully legal.

1. Regulatory Status & Medical Safety

FDA Determination

CELLIANT® infrared fibers—the engine of KYMIRA® technology—are FDA‑determined medical devices and general wellness products.


This determination is based on their intended effect on local blood flow and
tissue oxygenation in healthy individuals, and their classification as low‑risk, non‑thermal, non‑powered textiles.

Not a Therapeutic Device

The FDA determination does not constitute clearance or approval, nor does it classify the garments as therapeutic or diagnostic equipment.

This ensures full eligibility under competition rules, with no elevation
into regulated device status.

2. Safe Under All Anti‑Doping Regulations

KYMIRA® Infrared fabrics:

- Do not release any substances

- Do not alter physiology in a pharmacological way

- Do not interact with WADA‑prohibited lists

- Have zero chemical transfer risks

Our fabrics work by absorbing body heat and re‑emitting infrared energy, not by adding any foreign agents or stimulants.


This makes KYMIRA® fully compliant with WADA, USADA, UKAD, NADA and other international anti‑doping authorities.

3. Approved for All Tier‑1 Competition Environments

KYMIRA® garments meet kit and equipment rules across global professional sport.


This includes:

- NFL

- NBA

- MLB

- NHL

- NCAA

- EPL & European Football

- World Rugby

- International Athletics & Olympic sport

Our products are classified as standard performance clothing, not equipment requiring disclosure or approval.

4. No Electronics. No Risk. No Sanctions.

Teams often seek assurance around unauthorised electronics or smart-device violations.

KYMIRA® Infrared fabrics:

- Contain no batteries, sensors, transmitters or microelectronics

- Do not store or transmit data

- Cannot interfere with GPS, HR monitors or player‑worn sensors

- Are fully compatible with wearable technologies (WHOOP, Catapult, Polar, Oura, Hawkin Dynamics, VALD)

This ensures zero risk of competition sanctions and full compliance with all device policies.

5. No Heat Generation, No Thermal Risk

Infrared fabrics used by KYMIRA® are non‑thermal.

They use photochemical infrared reflection, not heat emission.

The technology:

- Does not elevate tissue temperature

- Does not increase risk in hot‑weather events

- Remains stable under contact, collisions and layering

Infrared output is produced purely from body‑emitted heat, not external heating sources.

6. No Compression Classification Issues

KYMIRA® garments:

- Are not medical‑grade compression

- Are not classified as compression equipment

- Can be freely worn under team kit with no approval required

This is especially important in leagues with strict uniform regulations, such as NFL, NCAA, World Rugby and Premier League football.

*Please note the Infrared Compression socks do have medical grade compression in.

7. Proven Clinical Safety

KYMIRA infrared textiles have undergone:

- Multiple human clinical studies on blood flow and tissue oxygenation

- Safety evaluations across sport, wellness and medical settings

- No adverse effects reported in trials

Clinical publications and FDA guidance confirm low‑risk, non‑invasive, non‑thermal operation.

Skin‑safe materials & no chemical treatments

KYMIRA uses bio‑ceramic minerals permanently locked inside the yarn, not surface treatments. This eliminates risks of rubbing, flaking, or chemical transfer, making the garments suitable for sensitive‑skin users.

Trusted by elite athletes & medical practitioners

KYMIRA is used daily by professional sports teams and high‑performance medical staff worldwide, demonstrating long‑term safety in demanding environments.

Priming soft tissues with KYMIRA Infrared for 30-90 minutes before training and performance, can reduce the risk of soft tissue injuries.

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.
