Sinus SP is made in a medium soft plastic chosen for its comfortable grip and feel so the durability isn´t the most important factor on this disc.
The disc has three grip areas on top with different textures. This gives players an option to find the grip and feel they prefer. Between the grip areas the disc is regularly smooth for players who prefer a smooth grip.
The flight is quite overstable making it useful in windy conditions.
This disc is a choice for any player who likes a good grip without it being too soft or sticky.
