This Moire is the largest version and uses a different vinyl coated mesh material than the smaller Moire pouches.
See-through visibility is pretty poor, but basic object shapes can be recognized so it is at least better than an opaque material. Instead of being breathable and drain ready, the pouch is actually close to water tight. The zippers and stitching aren't made to stop leakage, however if a liquidy mess occurs in your 12" Moire, the vast majority will remain contained. Like the other Moires, the format is similar having a main zippered pouch, then zipperd pouches on each side. One upper side has webbing for an attachment point while the other has a plastic rotating snap hook to give attachment options. In the end it makes a great travel organizer. The 12" is big enough to fit all of one's tolietries and then some more. The new material usage isn't necessarily a bad change, just has different properties. I personally found it useful to contain the stank of my dirty socks and underwear while traveling.
