Waterproof breathable trousers have a job scarpe manolo blahnik would appear to contradict itself. The first job is to keep wet weather out. The second job is to allow moisture from within (sweat) to escape. How do they pull this off?

To make a pair of waterproof trousers, you need to make sure that the fabric either repels moisture or is not permeable to it. Waterproof breathable fabrics do both.

On the outside they have a water repellent coating that prevents the rain or moisture from ever coming into contact with the fabric - it beads up and rolls off. Just in case the coating wears off or the moisture is just too heavy, there is also a membrane inside the fabric that has very small holes in it. The holes are too small to allow water drops in so the moisture is stopped before manolo blahnik scarpe gets to your skin. That takes care of the waterproof part.

But how do they make the fabric breathable? Remember the membrane with the holes? Well those holes may be too small for water drops, but they are big enough to allow water vapor (sweat) to escape. Since your body produces heat, the vapor rises through the holes and out into the fabric. Many fabrics are engineered to wick the moisture away from your body to the outside where it evaporates.

Of course all of this only works if you have undergarments that do not soak up moisture. If you wear cotton under the waterproof breathable garment, the cotton will soak up the moisture and manolo blahnik italia will not escape. Be sure to wear synthetics that do not retain moisture.

With proper use, you can stay dry and comfortable year round!
