Any jacket that doesnt have the seams sealed will leak given enough time (like that particular one). For me, I gave up on trying to keep dry and focused on keeping warm. Wear wool (or something that breathes) and something to keep the wind at bay. Start on the light end of layering and work up from there. The only thing that I really try to waterproof is my feet (cuz they get cold when they get wet), so I bought some nice cycling boots.
