A backpack is described that comprises a bag having a storage compartment, and a backpack harness configured for securing the bag on a user carrying the backpack. The backpack harness includes a pair of shoulder strap assemblies. Each shoulder strap assembly includes a weight-measuring device anchored to the top of the bag, so that when the backpack is carried by the user, the weight load applied to said each strap assembly can be determined. Each strap assembly can include a fastener configured for detaching the corresponding weight-measuring device. The fastener comprises a cylindrical member connected to a first strap section along the cylinder's wall, a tube-shaped member connected to a second strap section along the tube's wall. The tube has a longitudinal slit along its wall to allow the passage of the first strap therethrough. The first strap section is attached to the second strap section by inserting the cylinder in the tube. |
