“Checks all the Boxes”

Rip Curl Flashbomb Heatseeker Wetsuit


The first on our list of the best 4/3 high-end wetsuits is the Rip Curl Flashbomb E7 HeatSeeker. With the renowned reputation of Rip Curl, the Flashbomb Heatseeker is well worth the price. It’s described as “the most technically advanced cold water wetsuit” by professional surfer Mick Fanning: with the backing of this 3-time WSL world champion, the Flashbomb Heatseeker means business.

The Heatseeker contains a premium balance of flexibility, warmth, and durability. With comfortable E7 flash lining, the suit is exceptionally warm and one of the fastest-drying wetsuits on the market. In addition, the E7 neoprene is Rip Curl's most advanced neoprene to date.

What truly makes the HeatSeeker stand out is the Flex Energy lining in the back and shoulders, which produces heat when stretched. If you’re looking for a warm suit with complete internal taping that doesn’t lack comfort or flexibility, look no further. Lastly, we’ve found that Rip Curl suits generally fit best on lengthier athletic bodies, but if you are ever in doubt, give one of our experts a call.

Manera Magma Steamer - $559.00

“Performs Best in Cold Winter Sessions”

Manera Magma Steamer Wetsuit


Manera is a newcomer to Cleanline Surf, but it’s quickly established itself as a reliable and tried-and-true brand. Based in France, Manera prides itself on producing high-quality cold-water wetsuits for men and women. With that, let’s take a closer look at the Manera Magma Steamer 4/3 wetsuit.

First off, Manera uses a 3D computer system to design its suits, creating a true second-skin fit. From there, a "triplex magma" of materials makes up the layers of the suit. Re-flex skin is the exterior layer: known for its flexibility and durability. Next, air-foam neoprene makes up the middle layer and is super lightweight while maintaining impressive insulation properties. Lastly, Magma+ is the internal thermal layer. The fleece material provides the necessary warmth to extend your bitter-cold sessions.

Aside from that, the Magma steamer features GBS seams and SD2 tape applied via an air heater machine, which adds durability and flexibility throughout. Unique to Manera suits, phantom straps are located on each ankle, offering an additional barrier against the cold. See for yourself what Manera’s #notevencold really feels like in the Magma Steamer 4/3 wetsuit.

Take a look at our full review of the Manera Magma Wetsuit.

Highlights and Features

  • 3D design
  • Internally taped seams

Isurus Ti Evade - $589.95+

“Engineering Marvel”

Isurus Ti Evade Wetsuit


Isurus was founded in northern California - the perfect place for testing and curating cold water wetsuits. With a unique approach to wetsuit design, the Isurus Ti Evade is anatomically engineered with an arms-up design and bio-mechanical lat panel. The result? A less restrictive feel that enhances paddle power. Furthermore, Isurus’ supercharged compression design is a performance-enhancing technology that triathlon and Olympian athletes use, which reduces fatigue and increases range of motion, allowing you to surf longer.

With Yamamoto #40 neoprene on the upper body and Yamamoto #39 neoprene on the lower body, the Ti Evade is built for durability without sacrificing performance. Another feature that helps the 4/3 Ti Evade stand out is the Koregulator, an additional panel located on the lower back section. The lower back/kidney area is where the body’s main blood circulation organs are located, so Isurus implemented the extra panel to promote warmth. Don’t let the high price point steer you away; if you’re looking for the ultimate performance high-tech suit, don’t sleep on the Ti Evade.
