about the Shield 3.3 Zipfree Fullsuit Wetsuit

The 3.3 zipfree wetsuit from the Isurus Shield range. For those who want a little more warmth than the Shield 2.2 Zipfree wetsuit. The Shield 3.3 Zipfree wetsuit gives you 4 mm warmth in a 3 mm wetsuit. It is just better surfing in a thinner, warmer wetsuit.

The same Arms Up Design | Zero Shoulder Restriction paddling as the Shield 2.2. But with an extra mm of warmth. Giving you 4 mm warmth in a 3 mm wetsuit. So you can surf thinner and longer.

It paddles like a dream. It's the easiest wetsuit to get into and out of. The “Arms Up” design provides you with virtually “zero restriction” through the chest and shoulders. If you are tired of sore and aching shoulders after a session, than take a look at the Isurus Zipfree line.

The Zipfree entry has been improved for a better water tight seal. Still easier to get into and out of than chest zips or back zip wetsuits.

Life is just better surfing in a thinner, warmer wetsuit. Skeptical? Ask out in the line up.

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.

Reviews

2. 2 zip free and 1. 5 tops

"These suits are amazing we have over 70 1. 5ml tops that we suit our students up with in September and October. Water temps stay mild while air temps slowly get cool. Other schools have students in full suits and our students are amazed how warm there frames are and wearing less gear makes popping up on a surfboard for a brand new student much easier. These tops are wind resistant and we’ll see students from other schools in 3/2s with their teeth chattering and our folks are nice and toasty! I’m going to take a pic of our wetsuit rack and you’ll see it stocked with tops!"

Best in Class

"I decided to try Isurus recently and have been really impressed with the quality and construction. I started with the 3/3 hooded and have added the 3/3 zipfree and 2/2 zipfree. I recently wore the 2/2 on a mid-morning session at Morro Bay, water temp was 57-58, for an almost two-hour session. The flexibility, warmth and quality really put your suits in a class of their own. I can't see buying another brand moving forward."

— Teddy (5/5)

"Perfect fit, super stretchy and warmer than any other 3mm suit I have used before. Isurus is my new brand of wet suit!"

— Stephen (5/5)

FOUND IT!! After FIFTY YEARS of Searching!

"Been buying wetsuits since the 70’s and lived in Nor Cal for 30 yrs. The 3. 3 Shield is the hands down WINNER! I’ve searched for a suit that would keep me warm in chilly 50 degree water BUT allow me to keep pushing performance surfing. The 3. 3 Shield is as warm or warmer than any 5/4 or 3/4 suit I’ve ever had. , plus it’s lighter and way more flexible. This is the wetsuit they’ll bury me in!😜 But not for a few more decades! I love it so much I’m ordering another one to have for double session days! AWESOME 👏"

— Jim C. (5/5)

Another winner

"The Shield 3. 3 is my go to travel suit. From SoCal to France and Portugal. This suit is warm and super comfortable and packs great without the bulky zipper. BTW, I have just about every other Isurus suit for any season. They all just deliver."

— Mark L. (5/5)

Best Wetsuits Ever!

"Warm, flexible and superior performance with “gold standard “ materials. Before winters in SoCal & Nothern Baja were surfed with a 3/2 or 4/3 - for me one was too cold and the other too restrictive . Isurus’ 3/3mm zipperless solved that problem. Mind blowing comfort & flexibility and hot as a furnace. My wetsuit quiver was converted to all Isurus wetsuits as my old inferior big box brands wore out. This past winter my 2/2mm zipperless worked extremely well too. The extra money is absolutely worth it because it makes a real difference."

— Demetri V. (5/5)

3. 3 zipfree review

Best Wetsuits - Best Customer Experience

"Unreal wetsuit, it does everything as promised! Unbelievable customer experience as well, do not hesitate to reach out, Josh was amazingly helpful!"

— Michael (5/5)

Warmest wetsuit ever

"Best wetsuit ever for me! After several friends recommended the 3mm hooded suit, I finally picked one up. At 58 years old the cold seems to be the main deterrent. No longer! I’m toasty in all conditions. Thanks for helping me get more barrels 🤘"

— Thomas P. (5/5)
