Hi, I'm replying to the list in case others are interested. To my knowledge, Weather or Not is the only supplier of Solarknit and Solarweave. Solarweave is 100% nylon, Solarknit is knit cotton/poly. Solarweave is 13.95 yard I believe. This is a wonderful fabric and if you had been only able to buy the clothes before---as I have for the last 8 years---you would think the price is a bargain! I say this because RTW from these fabrics is $60-70. for a skirt, $50.-80. for a shirt and $70--$90. for pants. So you see, for us sewists, the price per yard is not at all bad by comparison. I have done extensive research on this subject, since I am extremely sun sensitive. The nylon is very lightweight and comfy even in high heat; I have worn them on vacation in Florida, because it's the only way I can go outside there in the daytime at all.
