This duffle seems to be made of nice durable materials.  It holds quite a lot (I just took it for a week's tropical vacation) and the zipper is durable enough to close the bag, even if the bag is a little stuffed.  The handles and strap appear well-made, and are comfortable to carry.

My only concerns regarding the bag are in the construction.  There seem to be a lot of loose threads around the bag.  I haven't seen anything that looks like it is going to tear loose, but I don't think I've ever seen a bag with so much loose thread.  I am hoping that it holds.
