The fit: 8/10
I've been struggling to find a binder that can fit my upper back but doesn't flare out at my ribs, but this one allows a good stretch around my lats and stays snug at the bottom, and it barely puts any pressure on my ribs, love that. It's easy to breathe in and easy to take-off.
What I don't like is that the arm and neck holes are kinda small, so it's not very stealthy and it's a little tight at the armpit (but at least it looks like a tank top). [I've ordered an XL]
The material: 10/10
I have sensory issues and I itch easily, but this one doesn't bother me at all, very soft, the materials feel natural.
Sweating, drying: 7/10
I didn't buy this for swimming but for everyday use during the summer, hoping it can handle sweating and dries up quickly.
Real summer heat didn't arrive yet, but I went to the gym in it. Isn't much more uncomfortable than a slightly tight sports bra, I could breathe surprisingly well the whole time, even when running, and I didn't get a heat stroke. It accommodated every movement and stayed in place. It got soaked but by the time I got home it started to dry up (still stayed damp but I'm not suprised).
