I've looked them up a bit and I love the idea that they can also just be rewaxed! However, I gotta admit I think right now they are a bit too expensive for me. Most of them easily cost two or three times as much as the technical jackets I've been looking at. I will do some more research tho, and definitely keep that kind of clothing in mind just because I think it's a really cool way to make them weatherproof
I didn't even know fabrics like that exist, gonna look it up right away, thank you!
