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.

Technobutter 4 Firewall
The all new Technobutter 4 Firewall utilizes the recycled graphene fibers at a thicker pile to create a fire hot feedback loop. As the body heat warms the graphene fibers they conduct the heat back into the body.

TB4 Air Firewall
The next great thermal breakthrough made better with trapped pockets of air. TB4 Air Firewall uses a special lamination process paired with a core of aerated neoprene and a graphene fiber jersey to create the toastiest conditions.
