The Road Toads are what you want for our bikes, single layer, made better than they used to be, better zippers, etc. I like 'em because they breathe, come in hi-viz and pack small.
There are ones marketed to the Harley crowd, Hogg Toggs or something like that, they are two layers, rather heavy so they don't pack small, probly don't breathe as well.
The material is woven polyester, and we can argue all day whether they're waterproof or water resistant...... I've only gotten wet because water ran in the top around my neck or I didn't have the jacket down over my pants properly and got a wet crotch. Again, I like them because the breathe and I don't sweat to death like all the rubberized "waterproof" suits. You do have to handle them with care.
