Without sacrificing performance, the Blueprint is O'Neill's most sustainable wetsuit so far. O'Neill's Blueprint range offers mind-boggling minimal seams, flexibility, and warmth. The legacy of innovation continues with the latest TB4 materials and our most minimalistic panel design yet. The Blueprint uses the ultra-warm and stretchy TechnoButter 4 Firewall to introduce full coverage, including arms, body and low legs. Our warmest, highest performing, most sustainable wetsuit to date.
