What are the best non-metal straps for Apple Watch?

I've been using my Apple Watch for work. I’ve never been so happy for a useful device. The only inconvenience is that I’ve been having those reactions because of the metal underneath the straps. It started from the top. I tried to loose it up but I still got some rash also at the bottom. I tried to put it on my other arm but I didn’t risk to keep it and it started to do the same thing. I was wondering if there was a possibility of getting new straps that doesn’t contain metal underneath.
