3DL™ Styles

New advances deliver a 3DL™ style for every sailor.

When North Sails first introduced 3DL™ moulded sails in 1992, they offered an unprecedented combination of low stretch, light weight, easy handling and amazing shape retention. Over time, we've worked relentlessly not only to improve 3DL™ performance, durability and value, but also to develop new 3DL laminates and layouts tailored to different sailing styles and a wider range of boat sizes. Today, North produces a light, fast, durable and affordable 3DL™ moulded sail that answers the needs of virtually any sailor.
