neilpryde spx95 sdm mastIntroducing the NeilPryde SPX95 SDM mast. More is less. Being a tiny bit heavier than 100% carbon masts due to a lower carbon percentage (95% and 90% respectively), the RDM and SDM fully convince with their durability, giving you extra safety and strength. HIGHLIGHT TECHNOLOGY SHARK SKIN TPX and SPX masts are finished using our unique, Shark skin surface texture layer. This low friction surface finish prevents wet materials from sticking to the mast
