The Kool is the result of a concerted reflection with professional teachers, to design a school harness according to Kortel Design. The design is optimized for use in paragliding schools, but also took into account the pilot progression, giving him a perfectly adapted harness perfectly for its first big flights. The rescue back pocket is integrated inside the airbag for easy extraction and optimal protection of the rescue. With respect to protection, the Kool integrates the principle of its big sister the Karma II with an integral airbag,pre-shaped right at take-off with a special foam. he Kool stands out from the Karma II at the level of the fastening straps. They comprise of two separate leg straps and one chest strap. The optimized positioning of these straps provides an excellent take-off mobility and increased comfort during kiting sessions.
