Isurus Ti Shield 3/3 Hooded Zip-Free Wetsuit

This wetsuit was born from a simple request by legendary surfer Peter Mel: create a wetsuit with the easy paddling of a 3mm zip free but the warmth of a 4mm. Isurus listened.

The New Ti Shield 3.3 Zipfree Hooded is the result of the reimagined Shield. Ideal for cold-water sessions, like the Santa Cruz California winter, Isurus infused it with their premium heat technology:

Isurus pulled down from their extreme cold water Alpha Series the Yamamoto Titanium Coating and plush Yellow Z-Fleece lining, along with the addition of their KOREgulator kidney panel providing an extra layer of insulation to keep your core warm and you surfing longer.

“I’ve been running the new Isurus 3.3 Ti Shield with the KOREgulator, and I’m seriously impressed. The KOREgulator tech keeps your body temperature locked in without feeling restricted — it’s that perfect balance of warmth and flexibility. You can stay out longer, push harder, and still feel fresh. This suit performs exactly how you want it to when conditions get real.” — Peter Mel.

This new addition was tested by Pete Mel himself and some of their most critical test pilots - the results were stunning.

This innovative combination has successfully boosted the suit's warmth to 4mm+ levels, completely eliminating the need for a bulky, traditional 4.3mm. You'll move more easily, paddle further, and stay comfortable in the water.

This will no doubt be your new cold-water favorite. Unmatched warmth and flexibility in this low-40°’s to low 50°’s water temperature range.

Titanium Coated Yamamoto (Ti) adds 1mm of Warmth:
While this might sound technical, the additional millimeter of warmth directly translates to your comfort in the water, allowing you to surf longer without feeling the chill. The Isurus advanced coating reflects body heat efficiently, making it feel like you’re wearing a thicker suit without the added weight or restriction.

Isurus' Quest to Build a Better Wetsuit
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.

Supercharged Compression
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.

Arms-up Design
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.

KOREgulator
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.

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