The Neil Pryde SPX 65 is an all new mast for the 2017 season that is sure to make your Neil Pryde sail perform at its best. The SPX 65 masts are made of 65% Pre-Preg carbon for the perfect uniformity of carbon and resin distribution throughout the mast. The SPX masts also have Neil Pryde's new Shark Skin texture on the pasts that allow the masts to slide in and out of the sails easily, even when wet. These masts have a Progressive Flex and Bend Curve that work best on Neil Pryde sails. These highly durable masts also come with a 2 + 1 year warranty. The masts are also available in SDM and RDM versions. Any sails with cams should use the SDM.
