About this harness
The Marshall brought hardshell thinking to seat harnesses: a premium Flexshell with a 3D moulded backplate that combines real back support with the freedom of movement seat riders rarely get. For foilers, racers and anyone who wants a low hook point without giving up modern shell support.
