You'll want to keep your perfed leather for the warmer weather. IMO there is not really such a thing as effective all season gear. The roadcrafter has minimal venting with some pit vents and exhaust vent on the back but no leg, sleeve or body vents so it is going to be like a sauna in 72F+ weather but excellent for your intended use, at least from from 72F to 32F. Because the roadcrafter doesn't come with an insulating liner, in colder weather you will need to provide a mid layer or buy the optional zip in, mid layer Aerostitch sells. Lots of info on the Road Crafter and other gear on ADVRider.com. Have you looked at other options? Motoport.com make stretch and mesh Kevlar one and two piece suits. The mesh gear should be ideal in hot weather plus they advertise it is the only textile gear approved for road race use by the AMA. Tiez and Olympia also make similar one piece suits similar to the road crafter at a reduced price.
Suggest checking out gear section of AdvRider.com for reviews.
