Got this thing from a family member, guess it was custom for the navy.  It's a ~60L stubby-shape Yates haul bag with a big dry-bag style roll-top closure sewn on the top.  I noticed it doesn't have a drain hole on the bottom like most haul bags, and the dry-bag top is pretty stout, so I suspect this is a full dry bag.  Haven't tested though.  Currently no waist band but there are loops where you could attached one.  Anyways, I don't do anything cool enough to need this.  Appears in brand new condition, doesn't look like it's been used.  No idea on age.  Not sure on price...$150, split shipping?  Feel free to make an offer.  Thanks
