I had the Milanese Loop with AW0 and it was very comfortable to wear even in the summer, probably because it could breathe. Putting it on was fast and easy too. But over time, after a year or so, the Loop wasn't as tight and I had to re-tighten it about 2-3x a day. A bit of a hassle. I now have AW2 with the Sport Band. When I wear it snug the band can flex/stretch for comfort just like the Milanese when I move my arm. If I want to wear it loose closer down to my hand I can since the Sport Band is also ridgit. I couldn't really do that with the Milanese because it's floppy when not worn snug. The Sport Band is not quite as easy to put on as the Milanese, but easier than a classic buckle. I read the Sport Band can be clammy during humid summer days, so I'll probably get the Milanese come summertime. I might try out the Moko Milanese which I can't believe is only $10 or so. Also, the Sport Band has a soft pliable feel too. What do you all think of the Sport Band?
