This is one of the most comfortable camera straps on the market, ideal for when you are using a long lens or working in demanding conditions.
it is designed to be worn cross-body, with the weight on your shoulder, rather than on the back of your neck (this model has the strap on the left shoulder).
The adjustable webbing strap is padded and non-slip, with locks to keep the camera at the hip. There is an underarm strap to prevent the camera sliding forward. This is helpful when you are crouching low or moving quickly.
The two straps lower the risk of a thief cutting the webbing and catching the camera as it falls.
The sling comes with a locking carabiner which clips into a fastening screwed into the tripod socket. This could be on the camera, or on the mounting ring of a long lens.
