The Dagger is designed from the connector links up with the demands of BASE jumping in mind. The Dagger is based on the proven reliability of F-111 7-cell canopies, engineered to be stronger and better in all the right places. It looks like a state of the art 7-cell on the surface, but a closer look reveals a beefier substructure and several other features that makes the Dagger a reliable choice for your BASE jumping canopy.
