The XO Siren model is inspired by none other than the one and only Susi Mai. As a leader in performance riding and a role model for many, it was an easy task to create a board suited to her needs and the needs of the growing population of women in kiteboarding. Our approach to developing the XO was to start from scratch and engineer this board from the ground up. The result is a performance freestyle model with a soft / responsive flex. Details like appropriate sizes and widths, narrower stance options and lighter weights all make this board the ideal choice for women of all levels.
