Using the new Fathom Alloy:
By integrating Premium Japanese Limestone Neoprene with newly developed Performance Jerseys, we’ve engineered a wetsuit that balances warmth, flexibility, and durability with a more accessible price point

New Material Combinations Blending Flexibility and Strength
Best-In-Class Wetsuits
Premium materials cost more. We want more surfers to experience ISURUS wetsuits. By combining proprietary Japanese Limestone Neoprenes and Jerseys, our Fathom Alloy provides incredible performance at a more accessible price point.
Alloys For The Win
Modern alloys make modern engineering, construction and technology possible. It means we can make better products at a lower price without resorting to using the same mass-market factories as 95% of the wetsuit industry.
Same ISURUS Fit & Design
Materials are critical to warm, flexible wetsuits, but the fit is also key. ISURUS wetsuits just "fit better" - and that's thanks to our panel design and arms-up construction. The Fathom Series features the same ISURUS fit that surfers love.

Testimony from the World Surf League Orthopedic Surgeon
Dr. Warren Kramer M.D.
World Surf League Orthopedic Surgeon
Newport Beach, CA, September 6, 2019
I've been fortunate enough to have used a lot of wetsuits. Beginning with the O'neill beavertail through the stiff fullsuits of the late 20th century, up to the present time. Many suits have their gimmicks: quick dry, neck gators, tight wrist and ankle cuffs, but they're still the same ill-fitting, moderately flexible suit.
Then a quantum leap occurred.
Isurus created a surgical glove
It's also exceptionally warm, with the flexibility in the shoulder and hips where it's needed.
As the Orthopedic Surgeon for the ASP/WSL for the last 25 years, I've seen a multitude of injuries from tight, poor fitting suits. The cut and stitch pattern is superb to allow exceptional flexibility through the shoulders. This decreases the risk of impingement syndrome and rotator cuff damage. The zipper less entry and exit is also very flexible around the shoulder which also decreases the risk of rotator cuff or labral damage.
I have also experienced myself the low back stiffness that occurs with a poorly fit wetsuit that allows low back chill. Even though the Shield is only a 2/2, the stitch and paneling is done to maximize fit with optimal warmth to the low back area.
Spend a little bit more on this fabulous suit rather than in my office with your shoulder pain. Buying quality never goes out of style. I rarely give testimonials, but I believe in Isurus wetsuits.
I don’t do surgery in garden gloves.
You shouldn’t surf in a suboptimal wetsuit
At Isurus, our passion is to build world-class wetsuits that stand up to the harshest conditions the ocean might offer.
Living and surfing in and along the California coast, a frequent topic of conversation was just how much wetsuit innovation had stagnated and quality had deteriorated. It is about designing a wetsuit that improves surfer performance.
