How does the Pursey fit around the waist?

The Pursey becomes a fanny pack as it is designed with 2 lobster claws at the end of the chain, that fit easily into each link of the chain. This creates a comfortable, adjustable fit so your belt bag stays in place. We have worn the Pursey around the waist in and out of the car, sitting, standing, walking, even in the restroom and it stays in place.
