The ProMaster Black Contour strap utilizes the stretchiness of the neoprene fabric to distribute weight while the curved design and softness further reduce neck and shoulder fatigue. A non-slip backing keeps the strap in-place without feeling abrasive. This straps length is highly adjustable with a range of 36 to 58. Strong quick release buckles are used at both ends. These buckles not only allow for the quick removal or attachment of the strap; they also form a carry handle when the neck strap is not needed. Just clip the ends that remain attached to the camera together. It is worth mentioning these quick release buckles are the same on all ProMaster Contour straps as well as ProMaster Tapestry straps. So, once you have attached the ends to a camera you can easily switch between any of these straps in just seconds.
