A new chapter in wetsuit innovation
O’Neill’s HyperX Stitchless wetsuit features Stitchless Seam Technology (SST), refined over two decades of innovation and testing, and paired with all-over TB3X high-stretch neoprene for warmer, longer sessions. Traditional stitched seams can create pinholes that let cold water in. O’Neill’s stitch-free construction eliminates leakage and boosts thermal efficiency — delivering improved warmth, reduced fatigue and exceptional flexibility.

Warmer. Dryer. More Flexible.
Stitchless Construction
Our pinnacle seam construction found in our high-end wetsuit series. All seams are triple-glued and fully sealed, blocking out water on both sides using internal TBX tape and our external 8mm silicone-based urethane Fluid Seam Weld.
FULLY TAPED SEAMS
This is the ultimate tape seal to keep you feeling dry and loose. 0.5mm split-neoprene is applied to all triple-glued seams with water-based glue, increasing the lifespan of all seam sections.
100% TECHNOBUTTER 3X
O’Neill’s exclusive TechnoButter 3X neoprene pushes the limit of flexibility to the next level. The buttery stretch and lightweight feel make TB3X a true game-changer.
Fluid Seam Weld
8mm silicone-based urethane-sealed exterior with a triple-glued and blind-stitched interior. Watertight, durable, and ultra-flexible seam.
