Key Features

  • The garment is made with our innovative Kynergy technology, which promotes blood circulation and tissue oxygenation.
  • Together, this improves cellular energy production – meaning your muscles will keep working harder, for longer.
  • Material will also speed your recovery thanks to the way it speeds lactic acid breakdown and reduces inflammation, meaning you’re ready to go, day in, day out.

Description

The Onyx Bib Shorts are designed to give you optimal performance and comfort on the bike, whilst also promoting recovery off the bike.

The shorts have a classic bib fit that is ergonomically designed to match your bodyshape and provide support to the muscles as they work, whilst the perforated grip bands hold the legs in place as you ride.

The LaFonte Vigor pad is longer and thinner than that used in our PrO2 bib shorts, and so is ideal for shorter rides.

The material used for the shorts is quick drying and breathable, meaning you’re kept cool no matter how hard your workout, and the jacquard race material used for the bib keeps you comfortable and able to fully enjoy the ride.

Infrared Benefits

  • Increased local blood circulation
  • Increased tissue oxygenation - by up to 20%
  • Increased cellular metabolism
  • Enhanced energy production
  • Temporary pain relief - experience a 25% average reduction in pain naturally
  • Accelerated recovery rate - from physical exertion, injury and surgery
  • Reduces Inflammation
  • Injury prevention - 80% average reductions in soft tissue injuries via muscle priming
  • Temperature regulation - warms & cools to suit your needs - clothing stores thermal energy 63% longer than standard fabrics when used as a base layer - fabrics dry 65% quicker than average fabrics
  • SFP35+ rating
  • Antimicrobial

Best Use

KYMIRA Sport products offer their best results when they are utilised across the full sport and training cycle:

Prepare | Perform | Recover | Rehabilitate

For the best results, our products should be used for every phase of exercise:

  • 30 minutes before performing - to prime your muscles to prevent injuries and to boost circulation and oxygen to train and compete at your best
  • During training and competitions
  • For at least 1 hour afterwards - to support your body to recover
  • As much as possible if you are rehabilitating an injury

The effects of the infrared within KYMIRA Sport products won’t diminish over time as the minerals are within the clothing fibres themselves. The infrared is continually beneficial, does not wear off with use, and the products are safe to use continually - certified by the FDA as a class I medical device.

Why IR50? Our Most Advanced Recovery Technology

- Boosts circulation to deliver oxygen and nutrients where your muscles need them most.

- Accelerates lactic‑acid removal, reducing soreness, stiffness and fatigue after intense training.

- Supports cellular metabolism + repair, helping you recover faster between sessions.

- Reduces inflammation and discomfort associated with high‑load training and repetitive stress.

- Temperature‑regulating infrared fabric keeps you warm or cool as needed, ideal for all‑day wear.

The technology behind the textile

The science inside KYMIRA’s infrared performance baselayers

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, supporting circulation, oxygenation, energy production and recovery.

How it works

From body heat to biological signalling, the technology is designed to support the body throughout movement and recovery.

01

Energy conversion

Body heat is absorbed by the mineral matrix and re-emitted as FIR light in the 6–14 µm range.

02

Nitric oxide activation

FIR exposure is linked to increased nitric oxide availability, promoting local vasodilation and improved micro-circulation.

03

Enhanced oxygen delivery

Independent tcPO₂ studies show that FIR garments raise tissue oxygenation, supporting aerobic energy pathways at a lower physiological cost.

04

Mitochondrial efficiency

FIR supports cellular energy and ATP production, helping sustain output and reduce the sensation of fatigue.

05

Biological signalling

Exercise studies show FIR garments activate signalling pathways related to mitochondrial biogenesis and angiogenesis.

06

Thermal balance

FIR helps stabilise micro-temperature during and after exercise, while the textile maintains breathability and moisture management.

Why it matters for performance

Designed to support sustained output, movement quality and rapid in-session recovery.

Power, strength & endurance

  • Improved oxygen delivery and faster aerobic system activation.
  • More efficient ATP production and reduced oxygen consumption requirements.
  • Support for sustained intensity, total work output and neuromuscular efficiency.

Movement quality

  • Enhanced local circulation and oxygenation help prime muscles for movement.
  • Support for mobility, flexibility, control and stability during high-speed movements.
  • Greater acute skeletal muscle adaptive responses during exercise.

Rapid in-session recovery

  • Supports the removal of fatiguing metabolites produced during exercise.
  • Helps moderate soreness and inflammatory responses.
  • Supports repair between efforts and training sessions.

Why KYMIRA supports injury prevention

Consistent movement starts with muscles that are prepared, oxygenated and able to maintain efficient mechanics under fatigue.

Enhanced circulation and oxygenation help prime muscles to be stronger and more flexible, supporting mobility and consistent movement patterns. Efficient muscular contraction, cellular energy support and reduced fatigue may help limit compensatory mechanics. Temperature regulation helps maintain muscle compliance, while recovery mechanisms support lower cumulative tissue stress between sessions.

Performance technologies should complement, not replace, a progressive training plan, appropriate warm-up, recovery, and professional medical advice where needed.

Size guide

The size charts below detail the relevant sizing or points of measurement for all of our products. Our garments do not need to be tight and against the skin for our infrared technology to work, so we suggest fitting to your personal preference. If you are looking for a looser fit, then size up from the guide's suggestions.
