The main material uses "Pertex Quantum Eco," which offers excellent wind resistance and abrasion resistance. The insulation in the waist and thigh areas features "PrimaLoft ThermoPlume+," a combination of two different shapes, providing high heat retention while still being lightweight and soft. Fleece with a durable hard-face print is placed in the inseam and below the knees to accommodate active running. The outer fabric is treated with a PFC-free water-repellent finish to handle some snow and rain. A zippered pocket on the center back of the waist can store small items like a smartphone. Despite the tight silhouette, the design minimizes restriction and pursues excellent movement tracking. Waist 38-40cm, Inseam 70cm
