the most suitable materials for rain clothes​

Answer 1

Among the fabrics considered most suitable for rainy days are wool, polyester, nylon or silk. However, silk might not be ideal in colder, wet environments. Instead look for materials like wool, which should maintain their warmth even if they do get wet.

Microfiber. Polyester microfiber material can have a special waterproof coating which makes it perfect for raincoats.
Polyurethane laminate. It's a very durable material that can also be a blend of polyester and cotton
