Sizing Chart: 


These lightweight bottoms are engineered for optimal moisture management during stop-and-go activities. Moisture is wicked across the garment via hydrophobic Phasic™ yarns that broadly disperse moisture, aiding temperature regulation by increasing evaporation and speeding dry-time. Encapsulated silver ion fibres provide long-lasting odour control.
