Snug as a bug
Used this bag with Highland 1042000 Hitch Mounted Cargo Carrier.  Winter, snow, salt and grime, it kept our luggage dry and undamaged.<br />Wish is was more flexible in colder temps.  Had to keep it in the hotel room so it remained supple for the next day. -1 star.<br />Has flaps which cover the zipper.
Rating: 4 stars
