5-time Disc Golf World Champion Juliana Korver reaches for her JK Aviar when it's time to ring the chains. This is a color glow version of our popular JK (Juliana Korver) Aviar. This special blend of durable Pro-line Plastic is more flexible and grippier than the other Aviar models. It has the same flight characteristics as the KC Aviar in a softer plastic. This makes it better for colder climates and those who require a tackier grip.
