Mountaineer is the high-spec Mizusawa Down jacket with non-stitch, heat-bonded quilting and seam taping for high water resistance. The 2023 model was also updated for enhanced comfort and convenience, with the addition of inner chest pockets on both sides and a detachable key chain for improved storage and a change to softer fabric on sleeve cuffs and inner collar. It features a Parahood System ※1 for compact hood storage and prevention of water pooling on the hood in bad weather. The front Dual-Zip Ventilation System allows fresh outside air to enter the jacket through a mesh panel between the zippers to clear uncomfortable heat and humidity. The lining uses warmth-retaining HEAT NAVI® to keep the inside of the garment at a comfortable temperature. In addition, it uses DOWNPASS ※2 certified traceable down, enabling the tracking of the entire feather procurement process through serial numbers.

※1 The Parahood System has a conveniently located Parazip to open and close the hood quickly and easily.
※2 DOWNPASS e.V (Germany) is a certification process guaranteeing down feathers are ethically sourced and come from tightly controlled and traceable supply chains, ensuring both animal protection and the maintenance of highest quality feather standards.
