watertight and secure
Holds a lot!  Securely attached.  We first put it in the matching cargo carrier (Pro Series 63153) rotated, with the TOP side on the BACK, and loaded it, then figured out what was the actual top (put the logo so the car behind you can see it).  Velcro enclosures and flaps kept everything dry, even in driving rainstorms.
