Introducing our most breathable rain shell yet. With our state-of-the-art TEK O2 technology, it's guaranteed to keep water out and let air flow for lasting comfort on and off the trail.
L.L.Bean is proud to introduce a first-to-market technology that redefines how breathable a waterproof jacket can be. We call it “TEK O2” because it uses a revolutionary nano-web air-permeable membrane to create a constant, unparalleled flow of oxygen. Water and wind aren’t so lucky – they’re sealed out, keeping you feeling light, comfortable and dry, even during your most active pursuits.
