Just got back from my first track weekend with my new SL-1. It fit great and did not inhibit my movement at all. It looks great and I got a lot of questions about it. I got the Tpro armor with it and I feel it was a very fair price for the fitment and quality. My wife measured me 3 independent times and I think we got everything perfect. I got the suit in 4 weeks, so great turnaround time.
Extremely pleased thus far. I haven't crash tested them "yet" and hope I never have to. Two thumbs up.
