The Pro Strap™ is rapidly becoming the choice of professional photographers and people who use large cameras with long heavy lenses. It's also ideal for use on portable power packs. The patented weight reduction system makes equipment feel 50% lighter and 100% more comfortable. The weight is evenly dispersed while the strap functions as a shock absorber to eliminate neck and shoulder fatigue. The Non Slip Grip™ adds the finishing touch which enables camera gear to be safely carried slung over the shoulder. You'll definitely feel the difference! The 3/8" Webbing Connectors give added adjustability and versatility so a camera can be easily worn across the chest if desired.
