The Grip6 offers what I believe to be a very simple but unique way of securing a belt but without using a traditional buckle therefore the belt lies flatter against the body, which is nice if you have something covering it, eg a sweater. The belts themselves are wide which also works with a lot of chinos and jeans that have wide belt loops and looks better than a thin belt. The only drawback is that because the position of the buckle is not fixed by any sort of pin, the belt can come slightly loose during wearing so I wouldn't use a Grip6 if I really needed the belt to keep my trousers up!
