Used this at Dreamstate and loved it. Everything is snug and not bouncing around when you're dancing.

I was never comfortable with a phone case on my arm, and generally just carried my phone in my hand, until I found this. It's just too convenient.

Super comfy, I forget it's there, and if I wanna snap a picture on the trail, my phone is still super accessible. I even wear it when I have my hydration pack on, because I don't need to fumble with zippers and stuff just to get my phone out.
