"Peter, in Beyond Backpacking Jardine recommends Polarguard 3D and Primaloft. Not sure if that's what he's still using in these kits. I bet they will kindly tell you if you email. The kit includes all instructions, fabric, insulation. Not sure about notions(threads, etc.)"
He would not. This is how he responded
"We supply the world's most high performance materials with our Kits. That's all we have to say about that. Enjoy your hike of the Florida trail, whatever gear you choose."
Doesn't give me that nice warm feeling inside that makes me want to buy from him. The rumor is he's using climashield XP now but I am very skeptical of this. He sells the insulation fabric for $2.95 a yard. That is RIDICULOUSLY cheap, unbelievably cheap, if it's XP. I'm afraid I'm shying away from Ray Jardine if he's going to be all mysterious with his products.
"I looked a few months ago, and Ray's website said the insulation was climashield. I believe the 2 weights are probably the XP and combat weights. I believe the fabric is probably nylon taffeta (ie: Ripstop without the thicker threads that make the square pattern). I don't know if it's DWR treated or not. His website talks about the benefits of a highly breathable fabric for keeping insensible perspiration from reducing the warmth of the insulation in quilts."
Never found anything about XP on his site. I question the use of XP b/c of the low price.
