I have the 2 piece version. For the price it's a nice suit. I have a similarly priced Teknic suit and it's not near the quality of the Joe Rocket. I've been down in it (low side) without any damage to me. A seam near the knee did pull loose but other than that it was only cosmetic damage to it. The seam was easily fixed by a leather repair shop. I paid retail for it.
I'd go for it. When I had the lowside in this suit, I got up and finished my ride for the day (another 300 miles). Nice to be protected.
