This travel pack combined with the EAGLE CREEK suit bag (not its official name) that i purchased at the container store have been amazing and really helped me organize my clothing for travel.  Its been a really nice feeling knowing where my clothing is instead of having to shuffle through my luggage to find something.  I bought this one first, and i'll probably get another.
The bags can fit a good amount, and the shirt folder is great, in that it can be filled with at least 8 men's shirts (i'm 6 ft tall and 195 lbs).  Overall the set is great, i'd like to see it priced a little cheaper, but i'm sure you can find a better deal than i did.
