ONE DESIGN LAMINATE

North Paneled laminates are woven by North Sails, and are the market’s highest-performance 2D laminate race sailcloth. A proprietary polyester resin system resists heat, water, and UV at a level unmatched by any string sail. Sails cut from NPL are significantly stronger, lower stretch, and lighter than competitor brands.
