Thermospeed race fabric is made of polyester (80%) and lycra (20%) with an inner membrane in polyurethane (85% poliestre, 15% lycra).
The outer fabric and the windproof membrane block cold air outside while keeping the body warm and comfortable.
The fabric is breathable, so it lets moisture escape.
The outer fabric glides when in contact with other objects (gates, velcro`s, zippers etc.) and therefore it doesn`t chafe; such quality makes the fabric more resistant and more durable.
The THERMOSPEED fabris is brushed inside.
