Those are similar to Mutazu's GA bags, only slightly smaller. Roughly 17"long, 10 1/2" high and 5 1/2" wide. I bought them on ebay with easy brackets for $80. I really just wanted the brackets, but I couldn't pass it up at that price. I put another bag on the parcel rack when I do an over-nighter or more, and you can't open the top loading bags with that bag on the rack.
