The 22 mm rim combined with the smooth Kastaplast plastic guarantee a comfortable grip, and the sharp profile and fast flight will give you a cutting edge on the long fairways. The Vass is a great disc for shaping lines into the distance but stay away from the Common Reed.
K1 Line is Kastaplast's super durable material with a nice combination of firmness and gumminess. Discs in K1 Line will appear in both solid and translucent colors. K1 Soft is similar to K1, but flexier and grippier. Just as with K1, this plastic comes in both translucent and solid colors.
