During the harnessing procedure, when should the sternum strap be fastened?

Fastening the sternum strap before adjusting the shoulder straps is important for several reasons related to safety and comfort. The sternum strap serves to secure the harness in a way that distributes load more evenly across the body. By fastening it before adjusting the shoulder straps, you ensure that the shoulder straps can be positioned correctly to provide effective support without slipping or allowing excessive movement.

When the sternum strap is secured first, it assists in properly aligning the shoulder straps when you adjust them afterward, ensuring a snug fit that maintains the integrity of the harness during use. This sequence helps to prevent the shoulder straps from digressing or becoming mispositioned, which could lead to discomfort or an improper fit if adjusted afterward without the sternum strap in place.

Overall, this sequence contributes to a more secure and stable fit, enhancing the safety of the user during various activities that involve the harness.
