The BASE EXTENSION 40 has been developed alongside our intensive race program. This product allows a shorter, softer mast to be used in certain sails to improve control and extend the wind range.

See the sail specifications for information on which sizes of REFLEX utilise the Base Extension 40 for premium performance.

The BASE EXTENSION 40 can also be used as a functional recreational product to increase mast length without updating your mast.
