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 oxygenation and glycogen storage in the blood, meaning your body has more energy available to utilise out on the road or trails.

The infrared technology also assists with recovery after the run; by keeping the top on for four hours after your activity, the increased oxygenation of the blood will improve the rate of lactic acid breakdown and cellular repair throughout the body.
