The blizzard jacket uses the 3-layer material "BREATH FLEX ™ THERMO" that has high moisture permeability (moisture permeability 10,000g), water repellency (water pressure resistance 20,000mm), windproof function and high heat retention of MEGABASS ™ EXTREME FABRIC series. A high-performance winter jacket developed for field athletes who challenge various outdoor activities. The outer shell always keeps you dry and comfortable even in harsh environments such as heavy rain and wind, and the inner part of the jacket is layered with a special hollow fiber material. Each hollow fiber takes in air and exhibits high heat retention and heat insulation effect without letting warm heat escape. It is lighter and more mobile than conventional winter jackets.
