Yeah, I have a dozen pairs and they're so much better than holding or wearing an arm band or waistband or anything. Yes, I miss just rocking my silkies, but I'm also 40, and the compression shorts provide comfort that definitely is appreciated.
I have a Pixel 9a and I've got room to spare in the sleeve. When I drive to races the other leg sleeve is for my car key. I've considered a weapon of some sort when I run through wooded areas, because I fear being attacked by bears or wildlife, which will never happen where I live, but it still goes through my mind when I'm back there.
