How long are your trips? Do you want a carry on, or a checked bag? Most bags that can fit two suits plus other items are too large to be carried on. I have a Tumi tri-fold that I received as a hand-me down. It is very small and cannot fit two suits without crumpling the hell out of them--and if you put in two suits you won't fit much else. Just right for a trip where I need to pack a single suit and maybe some casual clothes, but it does not fit my running shoes (let alone a second pair of dress shoes). However, it meets all carry on requirements, and can go in the overhead bin on even the smallest planes. I also have a Samsonite wheeled garment bag that easily fits two suits and a lot of other stuff, but is too large too carry on. My standard trip case for 2-3 day trips is a Briggs & Riley wheeled suitcase with a suit sleeve. This just makes it through bag checks as a carry on, fits one suit (two if carefully packed), some casual clothes, and an extra pair of shoes. I recently got a Swiss Army garment sleeve that is basically little more than a nylon version of the ubiquitous zip-up plastic suit bag, but which folds in the middle and has a handle on top. I plan to use this instead of the Tumi tri-fold, since it is lighter and simpler. My general plan for business travel is to underpack on suits, but overpack everything else. I always take extra shirts, underwear, and an extra tie. If you repeat a suit, people rarely notice or care, but if you repeat your socks and underwear YOU will ALWAYS notice and care.
