The XX® shoulder pad delivers a rock solid and comfortable carry when used on a 2-6 pound camera.   The upper comfort ceiling of 6-8 pounds is user-dependent and subjective.

The XX® pad is molded to a single 62" length of 600-pound test 1/2" kevlar web that will fit any standard camera connection.   Kevlar web is designed for the slot / bracket camera strap connection system.  

The 1/2" web and no-fail smooth stainless tri-glides (sometimes called buckles or sliders) provide a rock steady connection from camera strap to camera.   Nylon keepers keep the web ends neatly in place.
