These hip belts are taller than similar belts due to the locking aspect of the clip. Other participants use the tension of the winding to secure their position. I have both types. If I were to buy again it would be a "clip" strap.
Pros
The belt is great, you just have to put on the pants with no buckle for it to fit.
Cons
The buckle does not serve its purpose and does not close securely
