I just got a pair of the Cortech Apex Air perforated leather pants and their Magnum perforated leather jacket from Newenough and am very pleased with them. The fit, quality, and design are excellent which was really surprising because the price was hundreds below the competition.

I know this is the wrong time of year to be talking about perf leather gear but I live in South Florida. The jacket has a zip out liner that will probably be good enough for 50 degrees. The liner can be worn with or without the sleeves since they are also zipped.
The newenough fitting comments were spot on. I am not easy to fit but following their suggestions the sleeve length, waist, and knee protector locations were perfect. The pants and jacket zip together and should be permitted for track days at most venues.
The pants cost me $197.99 and the jacket was $224.99 with free shipping.
