Two Piece Yellow Rain Suit

Rain jackets can be made from a variety of fabrics, but polyester and nylon are the most common. These fabrics are slightly water-resistant on their own, but they need a boost from some additional technology before you'd want to take them out in the rain.

Wear a breathable base layer underneath to avoid trapping moisture in. Opt for merino wool or synthetic blends because these fabrics are wickable—keeping you dry and comfortable by drawing perspiration away from your skin—and they're quick-drying, so even if you do work up a sweat, they won't stay wet long.
