I have had an AirBoss for over a year and am looking to pack better using eagle creek packing. I have picked out a 18 pack-it folder, but am a little overwhelmed by the choice of cubes/sacks. I will fit my trousers and dress shirts in the folder, but what does everyone else recommend for undergarments, toiletries, and shoes? What sizes would be good for about a weeks worth stay?

Thanks for your help!
