I got the Alpine Loop band for my Apple Watch Ultra and, well, I immediately prefer this one to the Ocean band I initially got. Super comfortable, love the color, mechanism is great, and it's much easier to adjust. Recommended.
CaptainBackfire@viticci looks like it might be a little small on you? IIRC the clasp is not supposed to sit under your wrist as it can scratch your laptop or whatever is under your wrist at the time. I had to go swap mine out for the large version.
