Ultrafit strap questions

Hello

I need buy new strap, I think about ultrafit strap. I’ve read topics about this strap, byt I can’t find answers for few questions. Maybe someone use it and can answer.

- what about running, when You get sweat it’s start stink after some time ? (after activity I wash watch always with soap).

- Is this strap dry fast ?


- what about swiming also in salt water ? There are salt marks on it later ? 

Thanks
