This is a great bag which easily attaches and detaches from the passenger pillion of my Ninja 1000. The shoulder strap is a useful addition and makes it easy to handle the bag off the bike. My only complaint is that it would be nice to have an easily accessible pocket on the outside to store small items (sun glasses, change, etc). We drove through a lot of rain on our most recent trip and all my stuff stayed nice and dry. (Posted on 7/24/12)
I have several "dry bags" from canoe camping where you don't want your stuff to get wet if it comes to that. Heavy material and totally DRY.
I thought theses bags were way to elaborate and I almost returned them without a second look. I'm glad I didn't - there are so many features I'm not even going to try.
The BEST - the waterproof liner is white in color so you can see what is inside. One company that makes dry bags calls it the "black hole" - for good reason. You have to empty the contents to find anything.
So - excellent design and construction - lots of great features. You can strap these down in almost any direction with almost any combination of rack frame anchor sites.
