about the TI Shield 3.3 Hooded Zipfree Wetsuit

This wetsuit was born from a simple request by legendary surfer Peter Mel: create a wetsuit with the easy paddling of a 3mm zipfree but the warmth of a 4mm. We 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, we infused it with our premium heat technology:

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

This new addition was tested by Pete Mel himself and some of our 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.

Straight from the source:
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.

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.

Best wetsuit ever

"Best wesuit I've ever worn. 3/3 is warm enough for year round on the Central Coast where I used to wear a 4/3. Thing is so soft and flexible. Love it"

Evan R. (5/5)

"That's really the amazing wettie I have wear ever."

Miguel B. (5/5)

Great suit

"This is a high quality wetsuit! Highly recommend it!"

Stuart S. (5/5)

Wetsuit Review

"Amazing wetsuit. Warm, comfortable and very flexible. It fits better than any wetsuit I've ever had over almost 60 years. I love the zipper less style. As Josh said, it's easier to put on than one with a zipper."

Jeff R. (5/5)

Perfect wetsuit

"Really good wetsuits, warm and super flex"

OLIVIER D. (5/5)

Best Suit

"There may not be a need to own a 4/3 anymore! This suit is insane"

ZACH W. (5/5)

Gold Standard

"This is probably the flexiest hooded suit on the planet. By ditching the zipper, Isurus opened up the entire shoulder and back area. You don’t get that "tugging" feeling when you’re scratching for a wave. Im getting old and usually sacrifice with post sesh back pain but the flex on this suit has greatly reduced that. It’s a 3/3, but it punches way above its weight class. The Yamamoto rubber plus the hood allows me to have extended sessions. The suit is very warm and is great for those cold Southern California morning sessions. It doesn't soak up water. You stay light If you want to surf with zero restriction and no flushing, this is the gold standard."

Brian Z. (5/5)

The Real Deal

"I surf New Jersey year round, and I’ve been an Isurus fan for over a decade. But even I was skeptical when I saw the description for this wetsuit A 3 mil rated down to 41 degrees? Hard to believe, but I took a chance. Took it out for then first time today. It delivered. 42 degree water, 32 degree air, and blowing offshore. I was toasty in my 3 mil while most guys out were in 6. 5s. Get yourself one."

Indio R. (5/5)

Amazing

"This suit is unreal, able to surf in conditions that I normally would wear a 5/4."

David S. (5/5)

Best one yet!!!

"I have been using Isurus wetsuit for the past six years on this new 33TI shield it's absolutely the best!!!"
