O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Best/Most Flexible Suit Out ThereReview by Michael Michael
I have been loyal to another wetsuit brand for years, which also has a stellar reputation for great suits. I had tried other competing brands before and always found them inferior to that brand. However, after watching the recent Stab mag wetsuit reviews, which seemed real-world and unbiased, I decided to give this O'neil a shot because it received glowing reviews. In 10+ years of surfing, this is hands down the best suit that I have ever owned. This 4/3 is more flexible than other brands' 3/2 wetsuits. My recommendation is to watch the Stab reviews and even demo this suit if you can. If you can't try before you buy, just buy it (but know your size). I am now totally sold on Hyperfreak and will be converting over entirely for all suits as my current other thicknesses wear out.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Warm Suit and Amazing StaffReview by Brady Brady
The suit is exceeding expectations! As far as warmth goes the suit is unmatched and you will find yourself feeling like you’re in a hot tub out in the water! The suit came with a handwritten note, and some wax, which is awesome. I’ll definitely be shopping with Cleanline in the future!

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Excellent SuitReview by PatrollerOfWaves PatrollerOfWaves
Had two sessions now in this suit. Water temps in ~60-62º range. I'm skinny (5'-11"; 160lbs) and always get cold easy and stayed very warm (no booties or hood). Suit is extremely comfortable and soft, fits great, no weird bunching or extras. Flexibility is very surprising for a 4/3. When I first tried it on I was concerned about a little tightness in the shoulder area but once I was in the water I noticed no difference between this an a very well-worn 3/2 that I have worn for years. Honestly didn't even think about flexibility while wearing it in the water - basically its super flexible. After catching several waves in a row I started getting a little warm so I splashed some water inside but that's the opposite problem I've always had at this temp with 4/3s.

The zipperless is new for me so it is a little challenging learning to get in and out of the suit. Nothing overly difficult but having used to chest-zip for past 15 years it's been an adjustment. Still was easier than I was expecting.

Overall this is easily the best, most flexible, warmest, most comfortable 4/3 I've worn in 20 years of surfing.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Pure gloryReview by Chris Chris
Very similar mobility to a 3/2 with better warmth. Allows me to surf in SD without booties in the winter, love it. I don't think it's quite as warm as some other 4/3's, but no doubt it is MUCH more comfortable and flexible. I think it's the perfect suit for SoCal winters.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Warm and SnugReview by SurfMatt SurfMatt
I bought this suit 3 weeks ago and have surfed in it twice now at the BSR surf park in Waco. The first day, the air temp was in the 20's and water in the 40's! I surfed for two hours and the suit felt wonderful. The second day had air temps in the 60's and water in the 50's. I was in the suit for 8 hours straight and stayed warm until the last hour or so.

The suit is soft and supple and looks great. It's my first 4/3 ever as I just imagined they'd be too bulky compared to a 3/2. This suit is softer and more flexible than the 3/2 it's replacing. The zipperless entry is a bit of a squeeze to get into (watch youtube videos for tips) but I never once have had the suit flushed when going under water or wiping out. I would definitely buy this suit again. It actually has me excited about surfing all winter this year instead of taking a break.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Best wetsuit I have ever ownedReview by J J
In cold Ocean Beach SF ca, this wetsuit has been a true blessing. While I never write reviews, I can't say enough of this suit, Cleanline staff, and the flexibility of the wetsuit. Do yourself a favor and pick this suit up this winter. You'll have a great time in the water.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit AM i naked?Review by joshua joshua
I was in the shrill autumn waters of New England but it felt like I was sunbathing off the southern coast of St. Bart's with spider monkeys.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Amazing suit!!!Review by Rob N Rob N
This suit has taken me through 2 summers and 1 winter in SoCal.
It has worked in the 50 degree temp range with no real issue.
It's a TEENCY bit colder than some of the other 3/2 suits I have owned but the flex and drying time more than make up for that. Such a nice suit.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit love this suitReview by BlueJava BlueJava
Super comfy, easy to get on/off, plenty warm (water temp currently high 50's here in Central Cali). This is a wonderful wetsuit. I'm right in the middle of the size specifications for an MT. It was super tight the first couple of times I put it on, but loosened up a little and is now perfect. I definitely like the minimalist design. Great flexibility!

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Tremendous suit!Review by SharkBoy SharkBoy
Surfing in New England a 4 3 is essential as the water turns.
This zipperless did not flush at all and was easy in and easy out.
Water was 48 and I was toasty warm. Very flexible as well, felt more like a 3 2.
Technobutter 3 is the real deal and if you are looking for a 4 3 zipperless this is the one!
