Technobutter 4 | THE BEST, JUST GOT BETTER.
Innovation… It’s in our DNA. For 70 years, we’ve been pushing the boundaries of wetsuit performance and technology. This season, we bring you the evolution of this work and dedication to the wetsuit.
Keeping you warmer, Longer.
Graphene Heat Distribution
This trapped heat is then evenly distributed throughout the firewall via graphene fibres in the TB4 & TB4X liner, delivering balanced, full-body warmth without hot or cold spots.
Stay Drier. Stay Warmer. Longer.
O’Neill’s exclusive internal knit construction, channels water out of the wetsuit and provides even more insulation benefits. Keeping you drier and warmer, longer.
Heat Trapped at the Core
As the body’s core generates warmth, heat is trapped within the TB4 Firewall & TB4X Firewall, creating a consistent barrier that locks in warmth where you need it most.
Nothing traps heat as effectively as Air, nothing spreads heat like graphene.
We’ve combined our new TB4 and TB4 air firewall with our all-new,
buttery TB4X graphene-infused liner to create the world’s warmest performance liner.
TB4 Air Firewall featured only in Hyperfire wetsuits.
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 distribution.
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.
TB4 Firewall
The all new Technobutter 4 Firewall utilizes the recycled graphene fibers and a thicker pile to increase your warmth in the cold. As the body heat warms the graphene fibers they conduct the heat back into the body.
