I bought the belt for warm weather when I wear tight clothes. As I'm skinny and have a flat stomach, when I'm wearing a tight shirt over a regular belt the buckle makes a big bulge under the shirt which looks weird. This belt fades better than any other I've tried. For me, this works best with relatively thin dress pants like lightweight jeans, cotton khakis, and nylon hiking pants (much better than the inelastic belt that came with my Columbia pants). On heavier jeans, the elastic material of the belt doesn't work as well as a regular non-elastic belt and provides the secure feel I prefer. I think it could work better if the material didn't stretch as easily. But then it would probably be less comfortable, so it's a compromise. The adjustment slider works perfectly. It takes an extra second to move the clasp under the belt loops, but that's a minor issue for me.
