Top 7 Best 4/3 Wetsuits | Reviews (XCEL, Rip Curl)

Wetsuits have been a key piece of equipment for divers ever since Hugh Bradner invented the neoprene suit back in the 1950s. However, Jack O’Neill, founder of O’Neillpopularized using it for surfing. It’s rumoured that Jack discovered wetsuits first, but researchers have concluded that Hugh Bradner is the true “father of wetsuits”.

It’s already been almost 70 years, yet surfers still consider wetsuits as one of the most essential parts of the surf experience. Even a cold winter morning surf can still become enjoyable with the right wetsuit. This guide offers insights into what are 4/3 wetsuits best for, and which ones to look out for.

What are 4/3 Wetsuits Best for? 

One of the most important aspects when considering wetsuit warmth is the thickness of the neoprene, which is measured in millimeters. 4/3 wetsuits doesn’t mean its neoprene thickness is 1.33 mm. The first number represents the thickness of the neoprene in the torso area. The second number represents the thickness of the neoprene in the arms and legs. Thus, a 4/3 wetsuit has a 4mm thick neoprene in the torso and 3mm thick neoprene in both arms and legs.

4/3 wetsuits are best for water temperatures at  52-58 °F / 11.1-14.4 °C. You can happily wear a shorty wetsuit at those temperatures, but it’s not recommended. The thicker neoprene (torso area) in 4/3 wetsuits helps maintain your core body heat, which prevents hypothermia. The thinner neoprene is better for areas that are constantly in motion (arms and legs). We highly recommend checking the guide we made to better understand the correlation between water temperature and wetsuit thickness.

In 2017, O’Neill’s launched Psycho Tech wetsuits with TechnoButter 2 neoprene technology. It quickly gained a reputation for unparalleled levels of flexibility and warmth but lacked the resiliency that their other wetsuits had.

The Psycho Tech 4/3 fullsuit comes with O’Neill’s improved TechnoButter 3 neoprene technology that has an amazing amount of four-way stretch that enables better free body movement, lightness, and comfort. 

To top it off, O’Neill’s stitchless seam technology, together with its wind-proof smoothskin feature, prevents water from coming in. Alongside its plasma wrist and ankles seals, you can expect to be kept warm during every surf session.

Rip Curl’s Flashbomb 4/3 wetsuit is their attempt to shake the high-end wetsuit industry. Having the willingness to mix and match different grades of neoprene on various panels, they’ve created an optimized wetsuit for durability, flex, and heat retention.

This suit, in particular, holds emphasis on max stretch in the areas that require it the most. Experienced surfers who maneuver a lot will quickly love this suit and get most out of it. The additional stretch allows easier paddling motions, while panels in the legs make it simple to pop up on a surfboard or dig deep on a SUP.

#6. PATAGONIA R3 Yulex Front-Zip Full Suit

Men's R3® Yulex® Front-Zip Full Suit


  • Neoprene type: Yulex natural rubber
  • Seam construction: 100% externally sealed triple glued seam
  • Tape design: Low-profile interior tape
  • Entry system: Chest-zip entry
  • Available Color: Black

In general, neoprene wetsuits are not the most eco-friendly to produce and recycle. Patagonia tries to break the status quo by building their brand on eco-friendly neoprene. They do this by having their wetsuits made with a natural rubber technology called Yulex.

Yulex is harvested from a Guatemalan tree called Hevea. The renewable natural rubber performs just as well as neoprene, and it’s a far better choice for the planet. While neoprene is made in factories, natural rubber is produced by trees that absorb carbon throughout their life span. By switching to Hevea plantation, CO₂ emissions are reduced up to 80% per wetsuit.

Patagonia suits are serious go-to choices for durability and serious cold-water, especially their hooded wetsuit collection. This latest 4/3 iteration, the R3 Yulex fullsuit has recycled spandex thermal microgrid lining that dries fast and offers excellent warmth and flexibility. The suit’s Supratex kneepads and cuffs are durable, flexible and hold comfortably to the body without binding or restricting movement.

Even though Patagonia wetsuits are more expensive than other wetsuits, people who believe in minimized carbon footprint still buy them. But is it worth the price?

#7. QUIKSILVER Marathon Sessions 4/3 Wetsuit

4/3 Marathon Sessions Chest Zip Wetsuit


  • Neoprene type: StretchFlight neoprene
  • Seam construction: Liquid flex seal and blindstitched
  • Tape design: Internal tape
  • Entry system: Chest-zip or Back-zip entry
  • Available Color: Black

Quiksilver has a long history of providing the best wetsuit to even some of the world’s best surfers. They continually develop new technologies and design intricacies that sometimes become revolutionary. Like every company, they don’t hit the mark every year, but they have a tried-and-tested brand identity that means it’s hard to go wrong with their wetsuits.

Like its name suggests, the Marathon Sessions 4/3 wetsuit is built for longer surf sessions. This is possible mainly for two reasons: First, the infrared thermal lining design transforms body heat into warm energy, assisting the neoprene. Second, Quiksilver’s exclusive WarmFlight technology makes the wetsuit ultra lightweight and breathable warm. 

Quiksilver also made a big nod towards going eco-friendly with their wetsuits in recent years. Their WarmFlight technology is made mostly out of recycled PET bottles. Its lightweight StretchFlight neoprene is an eco-friendly alternative to standard neoprene that’s made from recycled car tires. They also use Aqua Alpha, non-toxic, water-based glue for their wetsuits.

For what it’s worth and what Quiksilver has been doing for the environment, it’s a solid and secure choice for beginner and intermediate surfers alike.

Frequently Asked Questions

Q: Should I choose a back-zip or chest-zip entry wetsuit?

A: It all comes to preference. Most people, however, prefer to use chest-zip entry since it is readily available to the user’s hands. 

Q: How do I wash my wetsuit?

A: To wash your wetsuit, rinse the wetsuit thoroughly inside and out with fresh water. Hang it dry in a cool shaded area and avoid hanging it in direct sunlight. You can also check our complete guide on how to wash effectively a wetsuit!

Q: Do you need to wear anything under a wetsuit?

A: You can wear your wetsuit with nothing (other than your underwear), and that is perfectly fine. But, it is still a matter of preference. You may also consider chafing and rashes that wetsuits may cause. If that’s the case, you may give wearing something underneath a try.

Q: How do wetsuits work?

A: Most wetsuits are made of neoprene, a kind of foam rubber filled with nitrogen gas bubbles that acts as a good heat insulator. Neoprene confines a thin layer of water between your body and the wetsuit. This layer gets warmed by your body, thus preventing you from losing too much heat while in the water.
