Hey folks, I'm James, the inventor and owner of the Jammock. Of course you don't "need" the Jammock (or SpiderShade), the same way you don't "need" lots of other non-essentials, but they're fun toys to have.
I look at it like this way:
1.) What's the cost vs. use ratio? (will I use this enough to justify spending the money?)
Answer: This one is up to you.
2.) What's the upkeep cost? (If I buy it and use it [or don't use it] what are my lifetime costs to keep up the product?)
Answer: Zero, the Jammock is low, low maintenance.
3.) What's the upside? Why would I buy this?
Answer: The SpiderShade looks great. It is a very attractive product, but it has only one function, and that's to keep some sun off of you when you're topless. Also, each SpiderShade piece can only be installed on its specific area.
The Jammock has a universal size that can go on many places on your Jeep, and is multi-functional (load-bearing soft-top, windjammer, sun shade, water-resistant bikini, extra storage area when another top is up, and tonneau cover [this on is a stretch, but it is possible]).
Here are some pictures demonstrating the versatility of the Jammock.
The tonneau cover is a bit of a stretch. The ladder picture is of two Jammocks.
Picture on the bottom right is with 3 Jammocks, the one on the rear roll bars can be used as a lounge chair.
