i've been using the same thing..waffle long johns with lined jeans.if i'm active,X country skiing,i'll just put on my gore tex rain pants over the waffles.thats worked to 10-20 below.for just walking the dogs i'll pull snow boarding pants over the jeans i'm wearing around the house.those were a good find,light weight and nylon with some sort of poly insulation, they are easy to wear unlike the heavy German military wool pants i was using.gaiters to cover the boot-pants interface are a must unless you have tall snow boots.i have lighter nylon ones i wear with jeans when i ski and it keeps the cotton dry around the cuffs.
