AWESOME PRODUCT!!!
Great product...100% waterproof, road tested from Pittsburgh to Myrtle Beach in the rain.  Not a drop got inside.<br />The straps that are attached to the bag are more than enough to tie to the cargo carrier that I bought.  However, I did use bungy cords as well (overkill).  This puppy holds an awful lot of beach gear.  Too much to list.  Would buy again and again....
