I bought the RST Pro Series Ventilator 4 suit with my bike, because I was looking for four season gear and was recommended these by the salesman at Peter Stevens. The first three months it worked okay, but add another three months and its leaking on top of my shoulders in hard rain, on my arms and on my stomach even in light rain. I suspect the zip-in liners are a bit of a design fail from the start. So, likely going to buy a Drymaster oversuit from RS Taichi. Here's the result from the light drizzle we had in Melbourne this morning and my 30km commute on the Princes Fwy. Not impressed. Could have spent a little more for better gear had I known this would happen. I also had some helmet hair crazy monkey edition going on this morning, but that's another matter.
