We created the Zipfree wetsuits from the ground up. Focusing on function and simplicity. The wetsuit is specifically designed to be ultra-light, flexible with extreme mobility. While still keeping you warm
Surf Hard and Fast. This Wetsuit Won’t Hold You Back
Shield 3.3 Zipfree hooded
4 mm Warmth In a 3 mm Wetsuit
• Ultra Warm, Yet Lightweight
• Less Weight And Rubber To Tire You Out
“By far the best, most form fitting suit I've owned over the last 25 yrs of surfing! Literally felt
like an extra layer of insulating skin rather than a wetsuit. Have my eye on the 2.2 for the
future!” - Jeremy M.
We believe to build the best wetsuit
You need to start with the world’s best rubber
Super Stretchy Yamamoto Neoprene
• Warmth Without Weight
• No Wasting Your Body Heat
Warming a Cold Water-Logged
Why do Isurus wetsuits keep you warmer?
Fact: Cold-water robs your body of heat 25x faster than air.
Yamamoto Neoprene only absorbs 2% water compared to 40-60% with competitive wetsuits.
You don’t get cold as fast because you don’t waste precious body heat warming a cold water-logged
“Who would believe this...
I surfed all winter in San Diego in a 2 mm zipless. IT’S THAT
WARM 🔥 Never in a million years imagined wearing a 2 mm in January”
Ultra Lightweight Warmth without weight
Absorbs way less water
• Keeps you less fatigued
• Less rubber to tire you out
Why are Isurus zipless wetsuits so light?
Isurus wetsuits made from closed-cell Yamamoto neoprene only
absorb 2% water weight. Most wetsuits absorb 40-60% of their
weight in water depending on their age. Less weight, so you don’t
tire as fast.
“O man! This wetsuit changed my life!
This wetsuit when wet is lighter up to 8 pounds the rest of the market! I’m just
lighter which allows me to turn almost as if I didn’t have a wetsuit!” Arthur R.
Starts Lights, Stays Light, Dries Fast
• Only 2% Water Absorption
• Means your wetsuit dries super fast
• No More Putting on a Cold, Clammy Wetsuit
• Perfect for those double session days
"The rubber is so silky... Not to mention it doesn't hold any water and dries super
quickly. You could have a session in the morning and by your afternoon session
your suit is dry without having to stick it in the sun.”
We believe design matters
Arms Up Design
• Zero Paddling Restriction
• Why Does Arms-Up Design Work?
The Zipfree line is designed with “Arms Up” which puts you in the optimum paddling position. Wetsuits are designed with the arms hanging at your side. Works great for streetwear, not so good for paddling. Think of how much restriction you get when you try to raise your arms overhead when wearing a
“You guys are onto something in wetsuit design.
There is a dramatic
difference between the Isurus 2.2 zipless and my “other brand” 3.2
when it comes to wasted arm energy. Much less resistance and
immensely improved paddle endurance.”

One Of The Top Experts For
Treating Surfers with Shoulder Injuries
“I have treated too many surfers who tore their shoulder ligaments getting into and out of tight, poor fitting wetsuits.
The Isurus Zipfree allows for exceptional ease of entry and shoulder flexibility...
I rarely give testimonials, but I believe in Isurus.”
"Stoked!!! Yeah dude, I’m still using the 3.2 Alpha from 2 years ago!!!! I still can’t believe its still
MADE WITH LIMESTONE holding up, I normally am a 2 - 3 wetsuits a year guy lol." – Chris B., Former Surf Shop Wetsuit Buyer
*Yamamoto neoprene has a much higher nitrogen cell content than competing materials.
And, this high cell ratio found in the Limestone based, Yamamoto neoprene, also results in
lower water absorption and increased durability over petroleum based suits.
Yamamoto rubber made from limestone, unlike natural rubber, does not deteriorate as quickly when
exposed to sunlight
