My mopar bonnet attaches right to the door surrounds. Completely water-tight roof wise.

 

If you will search the site, there are threads on this topic and guys who run the bikini, windjammer, and duster year round for the look. The bikinis for the JKU are one piece tops with a header channel and the Mopar one has the header made into the top. I'm on my phone or I would post a link.

I think I might have skewed this topic off course by mentioning the Mopar Sun Bonnet. I didn't realize that it is for front seat coverage only. I'm needing something to cover the back seat as well (for my little guy). Also, the last post mentioned a JKU and dusters / jammers. I'm trying to get feedback on just a safari for a JK. I do appreciate the help and I checked out the link you posted which had some valuable pics... thanks for that!

At this point in the hunt, it looks like the Bestop Safari + header might be the highest quality option for running doorless and providing 'some' rain relief. I'll take any other opinions though! Thanks to all.

 

The sun bonnet for the JKU covers all four seats.
