The Clasp Spine Protector from Ortovox is a separate spine protector specially designed for the Ortovox Freeride series backpacks, which have a separate insert on the inside of the backpack. The protectors are made from multi-impact SAS-TEC foam, which is certified to motorcycle standards. The microstructure of the foam barely gives way in the event of a fall with high force and speed, becomes firm in an instant and reliably protects your spine without really weighing you down.
