Description
Easy take-off, long glide
The Sonar Downwind series is designed to take off effortlessly at low speed and reach high speeds to follow faster swell: less drag and a longer glide, while keeping the manoeuvrability to move between bumps and maximum resistance to ventilation. The DW690 is the smallest: ideal for light or advanced riders, strong wind and big, fast swell, with excellent glide and surprisingly low take-off and stall speeds for its size.
Area 690 cm² · Pre-preg carbon
Who it's for
- Downwind riders, winging or paddling, who want to glide further.
- Anyone looking to link bumps in the swell with minimum effort.
