The Duotone EPX.90 is a 90% carbon windsurfing mast that makes high-end carbon affordable. Who says high-end carbon masts are unaffordable? With the EPX.90 Duotone makes exclusivity affordable for everyone.
The prepreg construction results in a dynamic reflex, a lower centre of gravity and improved durability. The autoclave manufacturing process eliminates excess resin and creates the strongest possible final matrix. The resulting layup is lightweight, durable and extremely consistent from mast to mast.
