Additional Info


Supercharged compression, muscle stabilization, and bio-mechanical lat panel combine to create a wetsuit that allows you to perform at your best. Increased range of motion, reduced fatigue, quicker recovery times and better overall circulation is what Isurus wetsuits are all about.


Just another gimmick? Isurus doesn't think so! Isurus Wetsuits were specifically designed around “Supercharged Compression”. Compression garments are known to improve performance and recovery. Professional and Olympic athletes in all sports use them because it improves performance and shortens recovery. It is long overdue for surfing, and Isurus is leading the charge.


An additional low back/kidney panel, or “CORE” temperature regulator is extremely important, as the kidneys are the body’s main blood filtration organs where all blood passes, constantly circulating and warming from the core – to the furthest extremities. This, combined with the improved circulation from Isurus Advanced Compression Design, increases body heat and enhances energy levels and shortens recovery time.


Isurus took a new approach to pattern-making for surf wetsuits. Wetsuit patterning, like all clothing (for the past 50 years) have been made with the arms hanging at your side, okay for street clothes, but for surfing wetsuits, it is restrictive. Isurus designed the wetsuit with the arms raised overhead. Putting your arms in the optimal power position for paddling.


Isurus has designed a one-piece side panel, stretching from the hip to the elbow joint, this provides unrestricted flexibility and maximum paddling power.
