Sternum System - Metal

Metal and aluminum sternum systems give backpacks a secure, long-lasting strap connection. They’re chosen when projects call for durability and a more premium finish compared to plastic components.

Makers use them in new backpack builds, outdoor gear repairs, and DIY sewing projects where reliable strap stability is key. With no minimums, you can order a single sternum set for a repair or enough for small-batch production.
