Old thread but I wanted to share my great experience with the R3 Light. I purchased it in CA 5 years ago before moving to the UK, knowing that as a daily motorcycle commuter I would need something absolutely waterproof. The R3 Light doesn't have a lining, which means you can modulate with the seasons. I always wear my work clothes plus the appropriate motorcycle layer. Nothing in summer, light layer in autumn and heated vest in winter. I took I size up on the suit so it all fits nearly. In the summer you can ventilate with stops at the front and at the back. Now, for the waterproof part. This suit has many UK winters (and Summers) under its belt, when rain is always available in large quantities! It performs perfectly as advertised. You can indeed ride for hours under pouring rain and get to the other side absolutely dry. However, as PanEuropean was pointing out, wearing a suit daily means that seams will stretch and seamtape will come loose. On the 3rd year I had to re-apply some tape (Aerostich sent some free of charge!) and on the 5th year I had the suit checked and fixed (taping, some minor fixes) by Aerostich. All in all, with 1000s of all weather, daily, short and long distance rides in that suit I would by exactly the same with no hesitation, there is nothing like it on the market.
