Anyone have a good arm band for gym/running that fits this phone?

This phone is great. I love it. But it's big (that's a PLUS and MINUS in this case)

I have been looking all over and I see the large number of phone case questions, but I'm looking for an arm band for gym and running. I bought one that's a sleeve and said it would fit a large screen size. It did, but not while the phone is in a case. (I use poetic neon's case)

So I ask, maybe a bit of a different question for this sub, but does anyone have a arm band for this phone with a case? I don't want to just leave it on a counter in the gym and it's too bulky for my pocket to carry at the gym.

TIA
