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.
