Additional Info

The lightest, stretchiest neoprene seam tape ever. 0.5mm split-neoprene applied to triple-glued seams with water-based glue to keep you dry and loose.

F.U.Z.E. CLOSURE
Front Upper Zip Entry (chest) uses a free floating zipper panel and anti flush barrier with drain holes to keep you dry and feeling loose.

Recycled Oyster Shells in Neoprene
O'Neill uses recycled ocean oyster shells in place of calcium carbonate powder which comprises approximately 10% of their neoprene.

Water Based Glue
O’Neill worked with their key manufacturing partner to develop a non-solvent based lamination glue called “aqua-alpha”. Aqua alpha reduces solvent usage by 600 grams per wetsuit compared to traditional laminating glues.

Eco-Friendly Packaging
Eliminates harmful VOCs and has the same durability as conventional, solvent-based Wetsuit glues. From recycled polybags to 100% recycled paper and soy based inks hang tags. Conserving water, energy and virgin materials. 100% digital catalogs.

Dope-Dyed Yarn
Dope-dying infusion produces colored yarns without the dyeing process. This saves tremendous amounts of water while reducing energy consumption and water pollution (up to 80%). 26% carbon emission is reduced for every kg of fabric.

Eco Carbon Black
Carbon black is one of the key ingredients in neoprene. It can now be carbonized from scrap rubber tires using high heat to extract. 72% carbon emission declined.

Area 52 Repair Center
O’Neill’s advanced repair facility prolongs the life cycle of their product, keeping their wetsuit out of the landfill longer.

Full O’Neill Wetsuit Sizing Chart

Fantastic suit!

Fits great, very comfortable, easy to get into. (The new model of the zipless version of this suit is very narrow at the shoulders/chest and was too tight. This suit is great!)

Hyperfreak Freaky

Went from an O’Neill O'riginal 4/3, to the Hyperfreak 4/3, and I am not disappointed at all. Movement is not compromised, nor warmth (even without the slick skin front like the “o”riginal). worth every penny!

Great suit and great service from clean line surf!

Very happy with this suit and the help of clean line surf website! Great quality, really warm suit I can’t feel the cold water in LA!

This is the one

I’ve tried most of the O’Neill wetsuits in their product line over the last few years and this is definitely the one to buy. Flexibility is superior, especially in the upper body, and warmth is very good. Easy of entry/exit is very good and gets easier with increased use. The only knock is the durability and the sleeves will be destroyed by leash or board bag Velcro, so keep away. The pros outweigh the cons on this suit. Here’s my 2 cents on some other suits I’ve tried, which ultimately led me to the Hyperfreak.

• Psycho Tech- I had my eye on this wetsuit for a long time, but when I finally ordered it, it was the worst wetsuit I had ever tried on. Ever. The material was so constricting, it was brutal just putting it on. Once on, I struggled to lift my arms above my shoulders and the legs were just as restrictive. Hard pass.

• Hyperfreak- I had the 5/4 hooded version for 2+ years and worked very well. I just wish this suit had a rubber chest wind panel.

• Mutant Legend 4.5- On paper, the best suit out there, but the fully detached zipper is extremely annoying to align when rushing to get into the water and when your fingers are numb when you get out of the water.

• Ninja- Had zero expectations for this suit, but gets the job done, especially for the once a month surfers out there. Not as warm as others, but very easy to get on. Great beater or car backup suit.

• I really miss the Superfreak, which is no longer made, but that suit had the perfect balance of flexibility, warmth, durability, and had the rubber chest panel. Hope this helps your search!

One of my favorite suits.

This is my 3rd Hyperfreak 4/3 and I hope O’Neill doesn’t change a thing about it. Super stretchy and plenty warm for me year round. I do bring some of my own insulation as I’m a fat guy and O’Neill is the only company that cuts a suit realizing fat folks surf too. So an XXL O’Neill suit truly fits as an XXL should. I’ve had a few other brands double X and they need to learn from these guys. The O’Neill Mutant was my favorite suit until I tried the Hyperfreak. So, as long as they don’t change too much on it. I’ll keep on using them. Also, thanks Cleanline crew for always being rad folks and keeping tons of stuff in stock.
