What is the difference between water-resistant, water proof, Gore-Tex and Maximum Vapor Transmission boots?
These are all terms referring to the degree to which water is preventing from leaving or entering the boot material. Water resistant: Water is somewhat prevented from entering the boot Waterproof: Water is prevented from entering the boot Gore-Tex: Water is prevented from entering the boot, but moisture (small particles of water are allowed to leave. The boot has a membrane of Gore-Tex which allows this small miracle to occur. Maximum Vapor Transmission: allows water and vapor to pass through the boot. Cooler, but not resistant to water!
