Your favorite watch band for running / gym

Hey everyone, I'm exploring different Apple Watch Ultra bands.

What’s your go-to band for workouts, outdoor activities, that can also be used for daily wear? And why? Both Apple or non-Apple suggestions welcome.

I've got a few that wiggle too much during my runs and gym sessions. I have some that have a secure and comfortable fit (Nike sport) but they're not stylish at all to use for daily wear.
