The O'Neill Blueprint series continues a legacy of innovation, featuring top-quality characteristics and high-tech construction made from the most sustainable materials currently available. O'Neill is dedicated to offering products with a high environmental responsibility. The design of O’Neill Blue products emphasizes durability, circular economy, and a better future. For this reason, they set the requirement that at least 50% of the fabrics in a collection must be made from more sustainable materials for it to carry the O’Neill Blue label. They are proud that over 80% of O'Neill's spring and summer collection consists of O'Neill Blue products - and they are aiming for more. They are on track to offer only the O’Neill Blue range by 2025.
