I have a Marathon Jacket and pants in AirMesh Kevlar and use the rain liners (top and bottom) and an electric jacket as well. I have about 45,000 miles on the set and they have performed well in all conditions. Liners are a bit of a pain, but they also add flexibility. In hot weather I generally don't bother with the liners as I am dry 15 minutes after running through a squall line. If the rain is going to extend for a couple hundred miles they are easy to slip into. In cold weather they do an excellent job of cutting wind and keeping a guy warm. When things get really cold, the electric jacket under the rain liner will keep a guy warm well down into the 20's. They have kept me dry in driving rain and in day-long drizzle. For dedicated rain gear, maybe a Gore-Tex set would be preferable, but they probably wouldn't vent and cool as well as the AirMesh does. They have worked well for me over the miles and I would recommend them.
