INFRARED TECHNOLOGY
Outdoor days test the body in very real ways: long hours, shifting weather, uneven effort, load carriage, poor sleep, and steady fatigue. What limits most people isn’t skill — it’s circulation, oxygen, and recovery.
Here’s how Kymira fits into that picture, without hype or gimmicks.
The Simple Science
Kymira fabrics are engineered with minerals that emit far‑infrared wavelengths (FIR) when warmed by your body. These wavelengths are well‑studied and trigger physiological responses that directly affect how your body performs outdoors.
- No gadgets.
- No batteries.
- Just physics and biology woven into fabric.
What Infrared Does
Improves circulation
Infrared activates the nitric oxide pathway. That relaxes blood vessels and increases micro‑circulation — including to hands and feet. Outdoors, that means:
- better comfort in cold wind
- less “dead‑hand” or “dead‑leg” feeling
- more consistent energy delivery
“I’ve suffered from mild Raynaud syndrome in my fingers and toes… KYMIRA Sport’s infrared technology increases the blood flow to my outer extremities and disperses the heat that my body generates.” Nikki Love — Ultra‑Runner & Adventure Athlete
Raises tissue oxygen levels
Independent studies show up to +20% higher oxygenation compared to standard fabrics. More oxygen = better endurance and sharper decision‑making.

Slows muscle fatigue
With better oxygen supply and improved waste removal, muscles stay capable for longer. This is one of the key differentiators you feel during multi‑hour days.
“Went on long night fly fishing trip last week and base layer kept me warm and comfy. It dried really quick too… Highly recommend it… Worth it though.” Angling Josh — Competition Fishing
Supports faster recovery
Even during rest, infrared continues to support circulation and cellular repair.
- Less next‑day stiffness
- Better readiness for day 2, 3, and 4.
- Reduced cumulative fatigue on multi‑day trips
“KYMIRA products — oh I wish I had known about them sooner! … The stiffness is reduced, pain during and after training is almost negligible and I am able to train again sooner too.” Suz Crichton‑Stuart — Equestrian
Helps maintain temperature stability
Infrared doesn’t heat or cool you — it helps your body stay balanced. Fewer spikes of heat, chill, or discomfort when conditions swing.
“Having tested and relied upon KYMIRA’s® products in some of the most extreme environments on earth, I believe they offer the most robust, adaptable and comfortable baselayers for any conditions.” Louis Nethercott — Expedition 5 Explorer
Why This Matters Off‑Grid
Whatever activity takes you outdoors and offgrid - angling, hunting, shooting, hiking ... however you like to experience the outdoors - performance depends on:
- Circulation to extremities
- Oxygen availability
- Endurance over long days
- Resilience to weather shifts
- Next‑day recovery
Infrared supports all five passively, while you move and while you rest. You just have to wear it! It doesn’t replace good kit or conditioning. It strengthens the physiology that underpins them.
The Research, Summarised
All these effects are documented in independent, peer‑reviewed studies:
- Tissue oxygenation: up to +20%
- Circulation: measurable increases in micro‑circulatory flow
- Fatigue: reduced lactate accumulation, slower fatigue onset
- Recovery: improved muscle repair markers, reduced soreness
- Temperature stability: more consistent skin temperature in variable conditions
Kymira Infrared supports the body’s natural systems — circulation, oxygenation, endurance, and recovery — in a way that’s measurable, researched, and immediately relevant to outdoor and off‑grid activity.
No drama. No big claims. Just science that makes long days feel better, and the next day feel possible.
