I do not know if there was an error in delivery, but the model I received a 2 hooks, but the model presentation on the site has only one. But that suits me perfectly. It ensures the maintenance of the chest, leaving him complete freedom of movement. It seems perfect for running. The fabric has a pleasant feel on the skin, maintenance is easy and the padded shoulder straps protect the skin from chafing during the effort, and whose length is adjusted to the rear.
