[Help] Looking for a specific type of watch strap

Hi! I was browsing through amazon, and came across this watch, and although im not a quartz guy, I fell in love with the strap

I couldn't find any felt watch straps anywhere, and skagen doesn't seem to sell their straps separately, so I was hoping to see if anyone knew where I could find something similar! Thank you!
