I recently traveled for a 4 day business trip.  I used this for pants and shirts.  the pants and shirt were all atleast "wrinkle resistant".  IT was nice because it kept my bag very organized and helped me fit more stuff, however the clothes still had some creases upon arrival.  I basically just hung them all up in the bathroom and turned the shower on , very hot, so it could steam the wrinkles out.  It did the trick.

Just be aware that you will still have wrinkles....maybe not as many, but some.
