GORE-TEX fabric supplies the ultimate weather protection. Durably waterproof, windproof and supremely breathable: this technology lets you stay outdoors for longer. The GORE-TEX fabric membrane is sandwiched between the outer shell fabric and an inner liner. Microscopic pores cover the membrane This makes the membrane impermeable to moisture yet breathable so moisture from skin escapes easily. The result: you stay warmer when it’s cold and drier when active.
