The Most Stable Sigma Dart Ever!

Using the mathematical principles that drive Unicorn's UniLab program, the Sigma HS has been aerodynamically optimised to provide high in-flight stability.

Ensuring a more consistent board impact angle, your set arrives as an integrated unit fitted with Gripper 4 medium shafts and ULTRAFLY Sigma HS Big Wing flights.

The alternative set-up of Sigma HS 7075 aluminium shafts with ULTRAFLY Sigma HS Plus flights still offers great stability but with enhanced accuracy. Sigma HS 7075 shafts and Converta points are made of aviation grade aluminium which is able to match most steel alloys in terms of strength and is one of the strongest aluminium alloys available.
