O'Neill Hyperfreak 4/3+ Chest-Zip Wetsuit • 2025

Started buying only these suits about 5 years ago because as an older guy, it was tough getting in and out of chest zip wetsuits. And these are ridiculously easy to pull down past the elbow and get out of. Sucks after a long tiring session to have to ask for help pulling down your wetsuit top ! And of course, this same stretch feature makes paddling feel almost unrestricted. Suit is also super comfortable and while not the toastiest, plenty warm for Nor Cal waters year round. I only have one complaint, the ribbed material on the outside of the suit tears very easily. This doesn’t hurt the functionality of the suit, but it looks pretty ratty. I’ve pretty much accepted that I replace it every year, which is around 25-35 surfs and worth it to me. A perfect reason to buy from Cleanline when they’re on sale !! Cheers

I want to thank the great team at Cleanline Surf Shop. All of their reviews and product information are incredibly helpful. When the order arrives, the packaging is excellent and even includes some nice gifts! The O’Neill 4/3mm wetsuit was a great choice and performs perfectly.

Great wetsuit. Very warm and keeps water out. I shopped around online and Cleanline had the best price and free shipping. Found a discount code online which brought the price down further. The free shipping was kinda slow, but no problem.

Suuuuuuper warm

I have this suit in a 5/4 hooded and a 4/3 hooded (New Jersey). Terrific suits. I had a question regarding sizing; got great advice over the phone; and have my new perfectly fitting suit. Cleanline comes through, again.

The suit is great! Better yet, this is my second order with Cleanline Surf, and I really appreciate how they treat their customers. Thank you for the little treats you add to the shipment (candy & stickers)!

I got my first O'Neil wetsuit back in the 80's and it was bright blue with neon green. I loved the ability to finally spend more time in the water when the temps dropped ...but that thing was STIFF and shredded my pits pretty good. Many years later and all the tech improvements have left me speechless at what a premium wetsuit can do. Aside from being a little tight around my neck (I have a big adam's apple) I have full flexibility and zero chafing, it's a 4/3 but doesn't feel bulky or restrictive at all and it's toasty warm but not overheating. I tried other brands over the years but the O'Neil just fits right without any fuss, where my Patagonia's never felt like they broke in and were perpetually stiff and my Rip Curl suits just didn't hold up and leaked like crazy. The only drawback is that it's a magnet for velcro and will fuzz up if your leash gets stuck to it so just be mindful.

Cleanline has top notch products and efficient delivery. But the highlight is the customer service! There was a hand written note in the box with the wetsuit I ordered for Christmas. And when I had to exchange the wetsuit because I ordered the wrong size, they made it completely easy and convenient AND gave me the same discounted price without me asking even though the sales had ended! Then, when I realized the replacement wetsuit might arrive before my son returned home, they delayed the shipping to ensure there were no delivery issues. AMAZING CUSTOMER EXPERIENCE!!

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!)

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!

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!

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!

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.

The suit is flexible as expected but not very warm for a 4/3+ I've got 3/2 that are at least as warm and just as flexible.. but as usually cleanline was the only place to buy products good service fast shipping what else could you ask for with a company. They are the best.

I’ve owned a lot of wetsuits, but this is the best one I’ve ever had. Worth the extra cost. Stretchy, warm and super comfortable. Stoked!

I am extremely happy with the Hyperfreak 4/3 suit - it's warm, flexible, and perfect for southern California winter riding. Keeps me warmer than my Psychotech 3/2!

I had an aging 3/2 that I used year-round, but I just couldn't brave another winter so I decided to upgrade to a 4/3 for the winter in SoCal. This keeps me very warm, and has great flexibility for paddling. Very snug fit, keeps me warm with no cold water flushes, even if I get rolled around in a wave. Its not the cheapest suit out there, but the seems are water tight, and double reinforced, and I've never been so comfy in winter water temperature in SoCal. Thank you

Fits a little tighter than my O'Neil O'Riginal 4/3+, but has very good freedom of movement, and is nice and toasty. No need for booties or hood here on the CA central coast, water temps have been in the low 50's.

Great suit, its top third is very flexible and feels like you are wearing a 3mm/2mm wettie but warmer than two previous 3/2 mms Ive had. I would put its warmth as good but there are warmer suits at that thickness but they are more restrictive. I love the chest zip direction, no fumbling around trying to thread the zipper. Doesn't seem to let the wind chill in either, despite no obvious windproof chest and back pads that other suits have. The Hyperfreak is the most comfy suit in the market, for me at least. I don't know about the claim it feels like you are surfing naked but its certainly a joy to wear. Cleanline are reliable and efficient, deal with them.

This suit is comfortable and warm. Can't believe it's a 4:3. The cleanline staff was very supportive when I initially ordered the wrong size. Item arrived in about 4 days.

FYI. Watch any hook and loop Velcro as it will chew up the neoprene pretty good.

It's comfortable, warm and easy to get on and off!

No more sitting in the lineup freezing my ass off in 55 deg water. This is my first chest zip, I'm now done with back zips. Easy to paddle in, seems to be well made, very stretchy and easy to get in, what more could you want.

Love the suit, warmer than expected, which isn't a bad thing,, but easy to move in. Not the lightest but overall the best 4/3 I have. Shout out to cleanlinesurf.com for a smooth and friendly transaction to get me this suit.

I'm 6'4" and 145 lbs and I was having the hardest time finding the a wetsuit that would fit me. There were only a few companies who sold suits that would even fit my frame and as you might have guessed it, O'Neill was one of them. I bought the small tall sized suit and it fit perfectly. I couldn't even feel the water when I first jumped in it. I don't feel ANY buyer's remorse.

Comfortable and warm!

Amazingly flexible for a 4/3+ suit. I noticed the extra thickness right away but the flexibility of the suit more than made up for it. Thanks to the warmth of the extra .5mm I was able to wear it comfortably in 48 degree water here in NY.
It doesn't have all the bells and whistles of the high end O'Neill suits but it also doesn't have the hefty price either. The inner lining allows you to peel off the suit very easily which is definitely welcome.
Time will tell how the suit holds up over the course of the year. If possible I'll update the review in the late fall after having worn it for 4-5 months.

I no longer dread winter dawn patrol. This suit is SUPER flexible, warm, extremely easy to get on and off. And it dries pretty quick for a 4/3 because there is no extra lining etc. Makes the entire experience so much more enjoyable. I'm in Southern California and I was actually worried that 4/3+ might be too much, but that hasn't been the case. Water temps have been in the upper 50s and I've been very comfortable. (Haven't needed boots in upper 50s, which is nice. One less thing to dry.) It feels like it would still be plenty warm down to mid or low 50s. I usually buy the top-of-the-line suits, with all the fuzzy linings and smooth skin chest. But I honestly do not miss any of those features. This is just as warm as my high-end 4/3 Xcel and is so much easier on and off. Not so sure about durability because of the super-stretchiness, but it does make cold water surfing much more enjoyable. The zipper is plastic which feels a little cheap. But that's my only real complaint, and who cares.

This is a great wetsuit for the money - super warm for the thickness and so stretchy! It's as warm as my 5/4/3 Billibong and so light and stretchy that I almost forget I have it on. I sized it using height and weight on the size chart, and the fit when dry felt almost too small for me, but in the water it loosened up and fits absolutely perfect. Highly recommended - thanks Cleanline!
