These cubes are very light flexible material bags that have many uses and are very handy.  I like how you can see in the mesh front without opening the bag.  Seeing the content without opening it works great when you have several in your bag.  These are high end bags; the interior seams are bound and finished nicely.  It zippers completely closed.  I use these primarily in a duffel bag; it's what works easily for me when I travel by car.  By Air I use a soft sided carry on and move this into it, I really strive to travel light.

This one is the middle size and is really great for socks, I roll mine to keep them paired in the zippered pouch, that way it's easier to grab a matching pair when I need them.  If you are going to want more than 2 sizes, I suggest buying them as a set and saving a few bucks.  Here's the link to the set of 3.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Eagle-Creek-Pack-It-Organized-Traveler-System-Set/dp/B0050HHW54/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Eagle Creek Pack-It Organized Traveler System Set</a>

The larger full cube Eagle Creek Pack-It bags are great for shirts and various larger clothing items.  These make it so easy to grab what you need and still keep your suitcase organized as you travel.  I've found that once I've used enough items to combine things, I can then use one for "dirty" socks for example and then it's easier to know what goes in the laundry when I get home.

While these are designed for travel, they work great for daily use in work bags and more.  I like the smallest size for small cords, power adapters and other small items (I have one just with power adapters for various contries).  The material is very light, which is really necessary when using many in your luggage so they don't get too heavy and push you into paying over weight baggage fees.  If you have cords that are stiff, or items that need the bag to be heavy duty to help contain them, I've found these CLC bags very useful as they are made from a stiffer material that'll keep things from poking out.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Custom-Leathercraft-1100-Multi-Purpose-Clip-on-Zippered-Poly-Bags/dp/B0002YVBC0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Custom Leathercraft 1100 Multi-Purpose Clip-on Zippered Poly Bags</a>

Go ahead and get these, you won't regret it, in fact I've bought several sets now and we use them all!

5 stars, I love using these as I travel and go about my day.
