The Venture 2 jacket is supremely lightweight and packable, but provides fierce defense against Mother Nature's fury. This is an unlined, no-frills rain shell, designed to be stowed away in its own pocket and thrown at the bottom of a pack until the day you need it. It's reliably waterproof thanks to the impenetrable DryVent technology, which uses a polyurethane (PU) coating that consists of a tri-component, multi-layer formula for waterproof protection, moisture permeability and durability.
