What’s the difference between a closed bridge and an open bridge binocular?

The bridge of binocular is the space between the two barrels. Some binoculars have an open hinge bridge design, and some have a closed bridge design, which is basically a larger, single-piece hinge. Open hinge systems use two smaller parts of the bridge, so they’re typically lighter but may not be as durable. Closed bridges are very rugged but heavier.
