A high quality waterproof running jacket should be lightweight and meet the rigorous standards of ultra runners. The updated version of the Ultimate Direction Ultra Jacket does just that. Without getting too technical, the material used exceeds the standards set for by the Ultra Tour du Mont Blanc, and weigh in at a mere 5.6oz / 160g. With attached hood you can stay dry and even keep the bugs at bay. It's ventilated where you need it and has overmitts for your hands to keep them warm even if your gloves get soaked.
