• Length: approximately 68 cm (about 26.8 inches) (from the start of the foot pockets to the tips)

Important Safety Information:
Please note that monofins are not buoyancy aids and are intended for experienced swimmers only. Always use under appropriate supervision, especially when minors are involved.
