Gear made with 3-layer GORE-TEX PRO™ technology is designed for outdoor professionals in mind and made for serious enthusiasts who require the best weather protection available. As our athletes will tell you, when they’re scaling exposed peaks and exiting the cover of trees, a cold wind or raging snow storm could drop body temps fast, putting them in serious danger. But under Gore's extremely rigorous testing standards, only the ultimate water- and wind-proofing are passed. This revolutionary multilayer membrane system bonds to a thin, low-denier microstructure—Gore Micro Grid Backer patented technology—to enhance breathability, reduce weight and internal abrasion, and resist snagging, creating the ultimate performance powerhouse you can count on in the most rugged conditions. So, if you really want to take it to the next level, be like the pros and go farther, longer, and harder than ever with GORE-TEX PRO™.
