This is a ok duffel bag.  It is not very big but is enough to fit one change of clothes and a extra pair of socks. However, it is cheaply made. The fabric is thin and the zipper is weak. I have a feeling that the zipper will probably fail first.  Also, it doesn't have many pockets so I cannot put my shoes and my toothbrush in separate compartments. This bag is ok for infrequent gym goers but I wouldn't trust it in a end-of-the-world type scenario.
