iPhone arm band

Hey STers, I have an iPhone X in an otterbox defender case. A couple years ago I was able to find a armband that could hold the phone/case in its entirety to wear on my arm for running. Of course I cant remember where I purchased it and all signs of a company name are gone due to lots of sweat. If anyone has any recommendation for a replacement product I would greatly appreciate it
TIA

Not a big fan of armbands myself, but I’ve had good results with a Spibelt for holding my iPhone XR: https://spibelt.com/

Thanks! I’ll check it out
