These things are great!  I ordered the 15" size which is perfect for dresses and shirts.  I wanted something bigger for pants and for my husband to use for his larger clothing.  I can pack so much more in a smaller suitcase using these envelopes.  My clothes stay nice, no wrinkles and my suitcase stays organized the entire trip!  You can see though some of the mesh, so easy to find what you want to wear.  I take the board with me, sliding it in above the item I want to wear, making it easy to remove an item from the middle of the packing. If I unpack, I just put the envelope in a drawer, no need to find extra hangers! Great system!
