A jacket called the Deluge Pro 3.0? Must be waterproof. Hell yes, and then some – 2.5 layers of laminated waterproof fabric to be exact. But you’ll never feel clammy wearing the jacket. Because it’s breathable, too. For added protection, the hood is adjustable horizontally and vertically. And the hem is adjustable too. All to keep the elements out. It’s a Deluge, after all.
