About a year old or so.
Is it similar to the bikini top that covers a family cage?
Pretty much the same thing, but with a flap like the old long-johns;D%)
But we could probably make up one for a short bikini if that's what someone wants. We make them in-house, like most of our other upholstery stuff, so ask away if you have custom needs.
And finally does it work with the Bestop riser?
Good question. I was just about to answer with a "Whichever one you have." but I should double check because maybe it's got it's own mounting method for the front. Frankly I doubt it though, because it would be reinventing the wheel when not needed. If you already have one of the risers, you should be able to use it with this.
For any bikini/rollbar top needs, or for things like soft top storage boots and stuff like that, you can call in any time to see what we can do. Did a beautiful fill family bikini in a great looking special black material with cool orange piping to match his paint. Piece of cake, but he did have to supply the materials to keep the price down. We have to buy in bulk from our suppliers most of the time, where he was able to find a supplier he could get small batches.
Worked out extremely well.
