E3 CARBON tubes are made of a one-piece monocoque high-quality carbon part, without any glued connection or insert; the diameter of the tubes are reduced to an impressive 28mm, that along with the new curvature profiles and the ergonomic sections of the tubes, gives an unpaired rigidity to the boom, thus reducing the stress to the forearms and allowing an extended use under extreme conditions. The boom is lined by soft grip dual density for a best grip while sailing, with a vast range of colours allowing many customization options in the graphics. Back-end and front-end are made of 20% of elastomer nylon; the E3s feature a newly designed front-end very compact and perfectly integrated in the boom outline, a highly optimized blocking system at the mast insertion and a carefully manufactured back-end.
