Bought it with the white ocean band and got an after market alpine loop and trail loop. Most comfortable for me was the alpine loop, hardly felt it at all, then the ocean band was second. Looks bulky but hardly feel it there, even during sleep. The trail loop was too itchy and made it sweaty for me

Congrats, looks good.

But too be sure, post this in r/applewatchultra and ask if the watch is too big. They love this question =)
