I’ve always felt the sport loops (soft w/ velcro) provide the best contact with wrist while not being too cumbersome. Very easy to tighten just before a workout or loosen before bed. All the while it stays planted on my wrist. Unlock the rubbery band it normally comes with, which is prone to sliding around and less easy to adjust.

Out of curiosity, which band do you use?

I also switched to the sport one and I like it because I sweat a lot and use it while swimming and it dries quickly. But if I don’t wear it uncomfortably tight while sleeping it gets looser probably because I move a lot while sleeping. One thing I noticed is that the biggest drops in measured o2 levels happen while I wake up to go to the bathroom. Normally it only measures while your wrist is flat and the watch is facing up but it is probably not able to detect it that quickly.
