I was playing with my Vapor today and when I put it away to go to the office, I focused my mind in the sail. I was just wondering if somebody knows what Prism used in the Vapor sail to build a so light kite, are the panel made with icarex or other? And what about the material of transparent panels and leading edges?
To save weight in each part of this beauty, Prism didn't use the regular mylar and dacron, so what were used?

From BFK:- The sail is constructed with film laminates, monofilm and .6 oz Icarex Polyester.

The Vapor sail material is truly amazing - the first time I put one together I couldn't believe how thin and light it is. 

I thought, hmmm.... a fast moving bumblebee could fly with through this stuff!

I'm just kidding around. Whatever they used was some serious stuff. A LOT stronger than it looks.

Judging by the finished weight of the Vapor, I don't think the sail material was chosen for super light weight. It's an 80" 5.4 oz kite and there are plenty of sub-6oz kites using conventional poly fabric.

That's one of the black rainbow Vapors that I lust after. I know there's at least two others that I've seen pictures of, I think one is in JC's photo collection.
I know Prism made a few white rainbow Vapors, too. Anyone know the scoop on these ? I have to have one of these, someday...

Amazing thing is the monofilm will stretch before it tears.....I've seen a few with stretch marks from upper and lower spreaders..............almost always these kites are damaged in ass/dissasembly mode and hardly ever in flight.....unless one were dumb enough to fly it in 10mph. Shocked

So..........the picture Sam...the picture?  pretty please?

Thanks Sam!

Yep I knew it was kite hill, and as it turns out I've picked up a couple of his kites including that PBSK, from the owner...(Vapor) if he still owns it............rumour had it that he had an all mylar Alien once too...........

Thanks to all for both fun and serious answers  Smiley indeed the feeling I have touching the transparent panels is the same of a food wrapping film. I put a lot of care folding the sail to avoid that a stand off ends to damage the monofilm and I have to agree with Tom also being aware to meet the flight of fast bugs  Smiley
So for what I read also the leading edges are made with Icarex as the sail.

Very nice dark Vapor, I wish I have one, and beautyfull collection of lot of all mylar and customs Prism classics, the second custom Alien seems to be purple and teal, if so it matches one of my two Alien, the other of mine is red and blue I think it's another one custom.

Diving into old Prism websites, they list it as ".5 mil. monofilm" which is equivalent to 0.0127mm. IIRC a lot of sail problems were related to this film getting creases in it and then cracking.

I flew a Vapor pretty much carelessly for a whole Pairs Comp season with no durability issues. No ugly rents in the monofilm after playing bumperkites. It's not a fragile as it looks, but I don't think it's as durable as Icarex. Any kite that flies that nice, I don't care what it's made out of.   Smiley
