Thankfully I find the Sport band very comfortable to wear. If I don't pay attention to the Watch it seems to fade away. Very light altogether. When I tested the bands at the store I found all cozy except the link bracelet. The Sport would be great to wear while lounging around the house but I don't find it too hygienic to use a band at the gym and during workouts then keeping it on my wrist the rest of the day. Since I was going to purchase an additional band anyway since the Sport won't cut it out for going out, I figure I can wear the higher-end band for the majority of the day and save the Sport for the gym. For all-day wear, are the Milanese and the Leather Loop as comfortable as or more so than the Sport? I would assume the leather loop is, although I will likely end up with the Milanese unless a third-party hurries up with a higher-quality band for less.
