Approx. 20 1/2 L at the longest point, 13 tall, and 7 wide.

One zippered full length interior pocket approx. 9 inches deep on the rear/back side of each bag (the side opposite the saddlebag opening / adjacent to tire)

Overall appearance and construction look pretty darn decent, especially for the price!

If I had any one 'gripe' it might be that the interior zippered pouch(s) should be located on the outboard (opening) side of the bags. Still, not a deal breaker for my intended use,,,

If you are looking for a set of bag liners that won't break the bank and don't plan on hauling 180#'s of bricks in 'em each day, these are more than adequate!
