Product Info

Don't let cold feet or slippery booties keep you beached. Slip on the O'Neill 3mm Hyperfreak Fire Split Toe Wetsuit Boots — made with O'Neill's new ultra-warm TechnoButter 4 Firewall + TB4X fibers — and confidently paddle out.

Product Details


TechnoButter 4 Firewall (Interior Sole & Interior Forefoot)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.

TechnoButter 4X (Interior Upper & Shin)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.
