Backpack suspension system
Overview
A backpack suspension system is the internal and external structure that supports and distributes the load of a pack, including the frame, harness, shoulder straps, hip belt, and adjustment points.
Key points
- Designed to transfer some pack weight from the shoulders to the hips and back.
- May include internal frames, frame sheets, stays, or frameless designs with supportive structure.
- Fit and adjustment of the suspension system influence comfort and perceived load.
Details
The suspension system of a backpack encompasses all components that interact with the body to support and stabilize the carried load. Internal or external frames, frame sheets, or stays provide structure, while shoulder straps, hip belts, sternum straps, and load lifters distribute weight across the torso and hips. Some ultralight packs use minimal or no rigid frame elements, relying on careful packing and softer structures for support. The way a suspension system is designed, sized, and adjusted can significantly affect how a pack feels over long distances, even when the total weight remains the same.
