I logged on today to see if anyone knew a vendor or another name for a fabric a friend told me is known as "mountain cloth."
I saw the fabric on the sole of my friend's dog booties. The fabric is durable, thin, sewable, and lightweight, although I don't know how light weight. My friend thinks it is sometimes used on heavier backpacks, on the bottom or lower half where you lay the pack on the ground and you don't want the fabric punctured. She also said it was once available from REI but I can't find anything that resembles fabric on their website.
I wanted to try this fabric for a more durable camp shoe than some of the clever sandals and flip flops shown on the forum, one to be worn in relatively cold (near frost) weather. I would use this fabric for the sole and around the toes for a bit of toe protection, probably a stretch tricot nylon upper.
Five trips last season my mountain camp fell below freezing overnight, so I am gearing up for a bit more warmth and comfort in an easy-on camp shoe next season.
