Naish have obviously been working hard on their entire range, with some new developments on the successful products from 2003. Launched late this year was their intermediate kite, the Boxer, which replaced the popular Aero II. This should continue to be a big hit next year. Joining it in the 2004 line-up is the latest in the X series, the X4. It looks like some serious refinements have been made by slimming down the construction a little to make the kite lighter in weight while keeping the durability high. As part of this, they have trimmed down the reinforcement patches around the leading edge, concealing them within the sail canopy for better streamlining.
