Question for "Longies" users

I use wool wraps but haven't tried a knitted soaker. I alternate mine between changes so they can air out. Are you using two pairs of longies and alternating them throughout the day or are you able to use them as pants for the day without them getting too damp? I would like to make some wool jersey pants and maybe try knitting some too. Just wondering how this was working for you all. BTW, my covers are only a single layer, so they definitely need airing. Will a double layer need it as much? I am planning to do my pants with two layers, at least where it counts.
