Pros:
* The zippers has stood up well over time
* The mesh screens allow for the socks to aerate

Cons:
* Inadequate depth
* Need to buy multiple for practical use when traveling

You can pack socks in a variety of fashions, but realistically it holds four to five pairs of crew socks if you lay them flat and zip it up. If you are packing anklets, it will hold six double layers. So whether this will work or if you will need to buy multiple will be up to what types of socks you are packing. If you are packing long, thick winter socks, this is nearly pointless because it will only fit one pair comfortably and two if you compress them and strain the zipper. I'm a huge fan of the Eagle Creek Pack-It system, so if you're a loyalist as well, you'll like this addition. I'd recommend at least two of these if you're serious about using them while traveling.
