DESCRIPTION
DESCRIPTION
Our longest stereofins for deep freediving and competition in dynamic.
The propulsion consists of large kicks with a great economy of gesture.
Composite blades to stock up on maximum energy throughout the bending.
Better strength and improved resistance to impact and crack propagation thanks to S-glass.
