Osprey Hydraulics™ hose systems include a convenient magnet mount design that makes tube management simple and easy. However, if you lose your sternum-strap mounted magnet fitting, you will be extremely unhappy. In keeping the magnet easy to adjust and personalize for set-up, Osprey developed a clip design that works great, but can be misplaced or wrenched off. Rather than make a big fuss about it, or permanently mounting the magnet in a fixed location, Osprey offers this Detachable Sternum Strap Magnet Kit, which features three strap mountable magnets to keep you hydrating steadily, safely.
