The Järn’s flight pattern makes it just as competent for touchy flex shots as for flat-out hyzers. It can handle headwinds and also provides a soid end-fade. Its low profile makes it easy to grip and to release. Järn is the Swedish word for iron.
 
K3 Line is Kastaplast's base line plastic and is grippy in all conditions. With this plastic you will get that nice worked-in feel pretty quickly. Compared to other base plastics, K3 Line is medium soft.
