Gore-Tex is made with a microporous membrane structure.
The Outback rubber outsole provides long-lasting traction and stability on rugged terrain. Rocky boots featuring GORE-TEX are guaranteed to be durably waterproof and highly breathable. We've got you covered with grip too.Each pore is much smaller than a water molecule, but bigger than a water vapor molecule, which means no external moisture - from rain, snow, sleet or puddles - can penetrate the membrane, but internal moisture from perspiration can easily evaporate.
