One note about size per the prior reviewer - larger may be better for men's clothing, but this is just the right size to tri-fold *women's* clothing (or children's clothing, for that matter.) The 18" Pack-it is too large to tri-fold all but my largest shirts, and a folding board is unnecessary if you're just going to fold things in half. This 15" folder will hold 7 or 8 of my small-to-medium size women's tees, short dresses, etc. and is the right width for ladies' slacks.
I agree with the comment that it could be lighter - the boards are pretty thick.

See my comments regarding the 18-inch Pack-It Folder, which I consider to be the better size for most usage. Certainly my 16-1/2 x 37 shirts, and even my short sleeve shirts, work better with the larger folder, BUT, if you need to pack a bag that won't take the larger size, this smaller size, which I continue to use for longer trips when I need two folders, usefully helps organize and give shape to something such as a smaller duffel bag. Of course, for some smaller adults, this size may suffice. I would allow that the Eagle Creek folders, while very durable, seem almost overbuilt; they perhaps should make lighter versions with ripstop rather than Cordura nylon, slightly thinner boards, etc.

I've used this product for many years, and it keeps my nicer shirts/sweaters/pants wrinkle-free, which is key when traveling with a backpack. Plus it can be molded to fit the amount of clothing you want to store.
