How are some garments/shoes advertised as both waterproof and breatheable? Aren’t waterproof materials inherently not very breatheable?
In: Technology
Waterproof materials don’t always have to be a shield that covers you! The diameter of water particles when in the form of liquid (think rain, puddles, etc.) are a lot bigger than that of water particles in gas form (the type that you let off and would want to allow escape). Waterproof and breathable fabrics often have very small holes, which allows for your perspiration to escape whilst preventing larger water particles from entering. Think of it kind of like a strainer or net
