The Kastaplast K1 Soft Jarn is an overstable approach disc built to punch through headwinds and sit down fast instead of skipping past the target. Kastaplast designed it specifically for flex shots and hyzer approaches, not straight putts.

Flight Numbers: 4.5 / 3 / 0 / 3

K1 Soft is a flexible, grippy blend, softer than the standard K1 line, and that extra give is what helps it land and stay put with less skip than a firmer plastic would give you. The low profile rim sits comfortably in the hand for both backhand and forehand releases.

Thrown on a hyzer it holds the angle and drops with authority rather than skating forward, and it handles a forehand flex line as well as any approach disc I've thrown. Headwinds barely move it off course, which makes it a strong choice for exposed holes where a lighter putter gets pushed around. It's a good pickup for anyone who needs a dedicated overstable approach disc rather than trying to make a straight putter do that job.
