How to use: You can use this shock cord to quickly tighten tarps or hammocks. Just thread it through the appropriate parts and pull it tight. For replacing cords in tent poles or jackets, carefully remove the old cord and insert the new shock cord. To fasten gear to packs, loop the cord around the gear and the pack. Note: Don't over - stretch the cord as it may lose its elasticity over time. When using it with the Tent and Tarp Line Locks, make sure they are properly attached. Maintenance: Store the shock cord in a cool, dry place away from direct sunlight. If it gets dirty, you can gently wash it with mild soap and water and let it air dry.
