Marathon is an ultra-light running short (weighing less than 70 grams) made using the exclusive Zero-Friction system to eliminate friction between the fabric and the skin. Seamless construction in the leg area, with just one seam in the middle of the shorts, prevents abrasion and improves comfort over long distances. Ergonomic elasticised waist ensures that the shorts always stay in the right position, while the 3D construction of the fabric ensures perfect fit.
