I have a lot of years and miles touring across the country on a couple of Honda 750's using a set of Craig Vetter nylon saddlebags.
Now touring on my CB, I got a set of Tourmaster Nylon Cruiser III Box Saddlebags - XL. I love these bags! They are have the capacity to hold everything I need for cross country trips. No need for a tank bag, which I hate. Eliminating the tank bag keeps the weight down lower and improves the handling of the bike and makes for a less cluttered looking bike.
I have them mounted under me seat and I can quickly detach them whenever I need to.
They come with stiff inserts that will keep the bags shape even when they are empty
Another thing I love about them is that they open with a top lid. So many saddlebags unzip from the side on down, making it possible to dump everything out when opened.
These are excellent bags for touring.
If you need smaller bags for everyday use I recommend you check
