I love these things.  I bought this set and I bought the set with 3 small ones.  It's really great for traveling and keeps everything organized.  In these small ones I used one to keep all my cords/chargers/converters which was awesome b/c it kept everything together and I used another one to keep all my socks (i was able to fit about 10-12  pairs).

In the medium size i was able to fit 12 pairs of boxers and in the large one I was able to fit almost 6 sweaters.

i loved them so much I bought my wife a set, my sister-in-law and father-in-law a set as well.  Everyone loved them.  Stop thinking about it...buy them.
