Fabric specification:

• Thermalite: Thermalite is a knitted fabric that is thermal and ideal at regulating body temperature as your body heats up whilst running. Thermalite is soft to touch and smooth next to the skin.
• Merino Blend:  A blend of merino wool and polyester fibres are fused together to produce a performance fabric with an extremely natural feel. Merino is highly regarded for its exceptionally soft and fine yarns that combine perfectly with the technical benifits of a synthetic fibre.
