Kastaplast’s glide-heavy understable midrange in K4 soft hybrid plastic. The Svea carries long and straight on any line you set, with an extra gummy grip and a floaty feel.

The Svea is Kastaplast's go-to midrange for players who want maximum glide without the low-speed fade. It holds any line you give it — straight tunnels, long turnovers, smooth hyzer-flips — and just keeps floating. K4 plastic puts that flight in a soft, extra-grippy hybrid blend that sits between base and premium, beats in at a natural pace, and happens to float in water.
