I purchased this gunmetal black belt in hopes that I could find a flat belt that would not rob up against my shirts that are snug in the front. I’ve had several Cami shirts get ruined by my previous belt. It is actually more like a dark smoky gray. But with the exception of a white shirt it really doesn’t show up through any of my shirts which is nice. I do like the slim design., It does sit flat underneath my shirts. The belt itself really doesn’t curl up in the back on my belt loop like some of my other belts do. The design isn’t too bad as far as how to fasten the belt, but I have one thumb that has a bit of arthritis in the knuckle. Sometimes it bothers my thumb to grip and pull the way you have to fasten the belt. And if you want to pull the bell really tight, it’s hard to get it Super snug. Because you can only tilt the buckle out so far to pull it tight. But so far I haven’t had any trouble with the belt itself. It holds perfectly, doesn’t slip, and does indeed sit nice and flat. I probably could have even ordered the slimmer size . Either way for the most part, The claims about this built right on target. It does exactly what it says it will do.
