Windsurf sail : freestyle Aerotech AIR X 3.7/4.2/4.7/5.2/5.8/6.4
The Air X is an awesome multipurpose sail. It excels at freestyle but it also freerides and wave sails nicely. It offers a lot of range on outhaul adjustment so you can tune it for your preferred feel. For 2009 this sail continues to be the best value in a 100% grid model. The sail has the soft feel of the Charge, but lots of power like the Phantom.
