Matt Says:

"The O’Riginal 4/3 FUZE wetsuit has replaced O’Neill’s Superfreak series for Fall 2017 and you’re mostly looking at a name change and a few cosmetic differences, but trust us that is a good thing. This means we’ve got a great suit on our hands here. This is your bang for the buck entry level performance suit. Packing in pretty nice features like smooth skin chest and back panels lined with carbon firewall, Ultraflex Neoprene throughout the entire suit, fully taped seams, and the best chest zip entry in the industry. Get this suit and go surf!"


A great balance of price and features, the O'Neill O'Riginal 4/3 Wetsuit provides reliable, long-lasting warmth. Utilizing modern technology, clean lines and the best possible fit, the O'Riginal uses stretchy and durable UltraFlex Neoprene and O'Neill's performance F.U.Z.E chest zip system. The O'Riginal achieves insane cold water comfort with a water shedding external smoothskin material on the chest and back backed with a super cozy Carbon Firewall lining to help insulate your core for longer, warmer sessions. All seams are triple glued and blind-stitched and then further fortified with a soft and durable internal neoprene tape on all seams to block water entry and extend the life of the suit. Pairing functional performance with moderate pricing, the O'Riginal Wetsuit ticks all the right boxes.

O'Neill O'Riginal 4/3 Chest Zip Wetsuit great valueReview by whatev whatev
First wet suit purchase in a long time. Super stretchy - super warm, but water temp is about 60. Front zip requires some Houdini maneuvering to get into / out of, but love the freedom once in it. Seems really well made.

O'Neill O'Riginal 4/3 Chest Zip Wetsuit Worth Worth Worth ItReview by mikey c. mikey c.
Great O’Neill front zip, with quick order processing and delivery from cleanline.
The suit, of course you need to be extremely pliable for entry/exit, its worth it! been a month or so and expectations have been exceeded. Wearing suit in
so-cal waters (winter19’). Was wearing a psycho zen zip 1 (loved it) but not going back to a back zip.
only issue, USPS ate half the box during delivery....thankfully suit was fully intact. cheers to cleanline and o’neill!

O'Neill O'Riginal 4/3 Chest Zip Wetsuit Warm and super comfy Review by Ashlee Ashlee
I got this wetsuit for my fiancé and he LOVES it. Says the material is super comfortable and keeps him warm in the cold pacific waters. He got the Medium and it fits perfectly. Shipping was a breeze and they even added some starbursts! Will definitely recommend and shop with Cleanline again!

O'Neill O'Riginal 4/3 Chest Zip Wetsuit Perfect Review by Mitchell T. Mitchell T.
I got this suit because I don’t like hoods and had a hooded quick silver. This suit is way better going from a 5/4/3 quicksilver to a 4/3 O’Neil it’s been great seals well and is pretty flexible to get in and out of. Drys at the normal rate. Never get cold in it even in winter weather and it doesn’t make you sweat walking to and from the beach! My go to wetsuit

O'Neill O'Riginal 4/3 Chest Zip Wetsuit warm suit for the money Review by marco marco
This is a warm comfortable suit for the money. I like the taped seams ,the front zip and insulation . The only thing it lacks is better seals on the wrists and ankles, otherwise it's still a all around durable, comfortable, and warm suit.
