The outer fabric uses PERTEX QUANTUM fabric, which is extremely lightweight and highly durable. The insulation uses PrimaLoft(R), which offers excellent heat retention and lightness. PrimaLoft is water-repellent, so it maintains its insulation even when wet, providing the same warmth as when dry. This makes it a great insulation material for harsh weather conditions. Both materials are very lightweight, providing a comfortable feel that you wouldn't expect from an outer garment. The high heat retention is also a key feature of this material. ・Design This is a reversible stand-collar blouson with a simple design. It's made with a relaxed, wide silhouette. The hem and cuffs are piped with ribbing to prevent cold air from entering. The nylon side has arm pockets on the body, while the quilted side has seam pockets along the side seams.
