Duotone Silver.70 Series - 70% Carbon Windsurfing Mast

The Duotone Silver.70 has 70% carbon content for a highly balanced price/performance ratio, and is Duotone’s bestseller.

All Silver.70 masts offer an impressive overall performance and low weight, achieved through the highest-quality carbon and processing with Aerospace Prepreg Technology. All RDM versions are technologically the finest needle masts, with the dynamic advantages of their slim shape (RDM adapter not included).

The white POLY.SHIELD coating on the base prevents scratches and potential wear, as well as thermal overload, and additional windings near the boom prevent any slippage. Provided you register straight after purchase, Duotone offers a two-year unlimited warranty; otherwise only statutory claims are possible.
