I am a new jeep owner. I have looked at some websites for jeep accessories. I have seen storage bags that are round, tube shaped that fit on the back of a jeep with the top down. has anyone used these? how well do they work?

I have the Clover Patch window roll and absolutely LOVE it. It keeps the windows safe and stored securely. (At least in the wheeling situations I've been in.) It's also nice to have them with you in case of sudden inclement weather. I've had mine for almost a year and haven't had any problems or concerns with it. Hope this helps!
