I'm looking for rain gear that works. I currently use a Rivet jacket and Rivet over pants. This works fine around town at town speeds. However it doesn't stand up to 3 hours of highway touring at 110km/h. Is there anything that will keep the water out for that lentgh of time at that speed? I'm also considering getting a new jacket. What are your thoughts on leather verses synthetics (linings, waterproofing, airflow, etc.), again with long range touring in mind.
