Thx! Artificial sinew. Ive tried using backstrap sinew but it is difficult to work with. I will likely only wear these in dry warm conditions. Buckskin is not waterproof at all.

Thanks for letting me know. My feat seem to either be cold, or too hot and sweating which then leads to freezing cold and wet. Over the years I've realized animal leathers have superior vapor and heat regulation qualities. Might have to make some for myself!
