I ordered 3 different bands. Two of the stretchy ones. Those fit ok kinda tight and I ordered the largest on both. I don’t have super large wrists. I’m a woman with large wrist but not as large as many men I know. I also got the slim perma band, no where in the description did it say how long it is, just that it is adjustable. I did submit a question asking how long it is and if it can be extended for larger wrists, that was never answered. After waiting 3 days I just bought it, it “fits” snugly. I’ll keep it but it’s not comfortable to wear for long periods of time. I would not recommend for people who have larger wrists.
