The Grom is the perfect sail for advancing kids. With a huge focus on weight, we built the lightest frame possible with 3 battens and used predominantly UV protected Bi-ply film. A soft dacron panel at the front of the sail, gives a nice forgiving power supply, accelerating quickly and easily on to the plane. Also featuring durable X-ply around the perimeter of the sail, giving structure and protection, for longer lasting performance. Whether kids are looking for their footstraps or already reaching for the sky, the Grom is the perfect partner.
