Technical Details

TECHNOBUTTER 4 - TB4 builds on the legendary Technobutter 3, the next evolution of the jersey introduces recycled yarns infused with graphene for increased wear strength and heat retention.

TECHNOBUTTER 4x - Technobutter 4x goes beyond the gooey stretch, and soft feel of TB3x. Recycled graphene fibers line the jersey allowing for incredible stretch with added strength and warmth retention, all with a new look.

TB4 FIREWALL - Technobutter 4 Firewall utilizes the recycled graphene fibers in a light and soft thermal layer to create a fire hot feedback loop. As the body heat warms the graphene fibers, they conduct the heat back into the body.

ROBERTO DE SOUZA JÚNIOR

"THE BEST OF THE BEST THANK YOU ONEILL I'VE BEEN USING THE HYPERFREAK SERIES SINCE 2018 SOMETHING LIKE IT AND IT'S A GAME CHANGER. YOU EVOLVE YOUR SURFING, GETS INTO AND OUT OF THE SUIT EASILY AND MOST IMPORTANT, STAY WARM. WITH THE FIRST ONE I GOT IMPRESSED BY THE LIGHTNESS OF THE SUITS (HAD TWO HYPERFREAK 3. 2 IN 2018 AND 2020). THEN I RECENTLY BOUGHT ONE WITH SHORT ARMS AND 3. 2MM AND IT IS SIMPLY PERFECT). AHH AND I HAVE ALSO A DEFENDER 4. 3MM, SOME GLOVES ALSO ONEILL AND NOW ANOTHER 4. 3MM, THE HYPERFREAK FIRE. I WILL KEEPING USING ONEILL SUITS ALL THE WAY, I ALSO HAVE A SHORTER ONE, LIKE TO WEAR ON SUMMER AND A JACKET."

Super nice. But, I swapped

"Super nice. But, I swapped for same size in the Back Zip. . . as for my size - right between XL and XXL (6'1", 218 lbs, 44 chest, 37 waist, 44 hips, 25 thigh) - while I don't have a barrel chest, I am slightly wider across the chest and shoulders plus have some weight/meat in legs/butt. So, the Chest Zip was a tad tough to get on, but mainly the zipper & seam across the chest pinched/pulled just a bit at the end range of motion (I kiteboard) . Swapped for the Back Zip = perfect for my athletic build as has more flex across the chest and is easier to get on/off overall while still being super flexible and snug at the same time."

Jeffrey B. (5/5)

Too warm

"Yes I said to warm! Which is a good thing I wore it in 61 degree water let’s say the water needs to be colder or it needs to be more of a windy day. This suit is so light and thin for a 4/3 not bulky feels sexy. Doesn’t way 30 lbs when it holds water like a rip curl. I wore a large 3/2 at a demo day and it felt like I had nothing on; so light and stretchy. I’m immediately purchasing a 3/2 of the same model as my 4/3. I am 6’ ft 175lbs but I have a larger than normal neck for my size and the large fits like a glove and doesn’t choke me out. I have to wear a double xl in rip curl or else the neck literally deprives me of oxygen."

Pete G. (5/5)

Amazing

"Amazing"

Mateo C. (5/5)

Worth it

"Still wakeboarding in November! Feeling great in Indiana. Water is 56, air 55 or so. When I’m done it’s still dry on the inside. This thing is the actual cheese buds."
