We're a bit disappointed that we couldn't get the webbing. It also took longer that usually to get answers to our questions.
I bought some to use as a tent floor, needed it to be tough, two kids and a dog. I am still in the middle of the project but it's easy sewing. I cut a little 8" × 8" test piece and tested it for waterproofing and it was great. I can not rip the piece of fabric with my hands and I turned my pocket knife sideways and scraped the tip across the non pu side about 7 or 8 times... trying to simulate a bit worse than dog nails... couldn't barely tell when I was done that anything had happened.
I used this material to make some packs and it worked great. 10/10 would use again.
unbelievable waterproof fabric, I did some tests - no water get in - excellent texture and many colors to choose from, soft but very strong.
