The best waterproof jacket for hiking is one that repels water while also being highly breathable and comfortable to wear. Jackets with a coating typically are less breathable, while jackets with a membrane usually offer the ultimate breathability. They’ll repel water while also letting air move in and out, and sweat moisture move out. For top water repellency, look for three-layer women’s hiking coats. These have a durable outer layer, an inner membrane and an additional liner inside, and they’re the most reliable, high-performance rain jackets. If you don’t need that much protection, opt for a two- or 2.5-layer jacket.
