The Core 3.0 top is a great choice for those looking to optimise comfort on their run. The top is made with raglan seams and our signature flatlock stitching to eliminate friction and chafing that can occur as you clock up the miles, whilst the supportive fit across the shoulders is aimed to promote good posture and thus boost performance as you run.

The top is an excellent go-to for day in, day out training, as the triple stitched hems and durable fabric will last everything that the environment can throw at it, whether that be beatings from the weather as you clock up the miles to prepare for a marathon, or the obstacles you encounter out on the trails.

The top is made from our infrared-emitting fabric, which helps regulate your body temperature as you work out, dissipating heat and evaporating sweat better than normal fabrics. Furthermore, this unique technology increases blood circulation, tissue oxygenation and cellular metabolism, meaning your body has more energy available to utilise out on the road or trails.

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.
