O'Neill
Jack O'Neill invented the wetsuit in 1952 — 70+ years later, the Psycho Tech and Hyperfreak lines are still the reference cold-water suits for millions of surfers.
About O'Neill
O'Neill was founded by Jack O'Neill in San Francisco in 1952 when he opened the world's first surf shop and started experimenting with neoprene to keep himself warm in cold Northern California water. That experimentation produced the world's first wetsuit — and 70+ years later, O'Neill is still one of the two or three most-reviewed cold-water surf wetsuit brands on earth.
The current lineup is anchored by the Psycho Tech and Hyperfreak ranges — high-end, TechnoButter 4 neoprene suits designed for cold-water performance. The Psycho Tech is the flagship: chest-zip or hooded, with the brand's warmest and stretchiest neoprene. The Hyperfreak sits just below at a lower price point but with much of the same tech. Below those, the Reactor II covers entry-level 3/2s and 4/3s.
O'Neill wetsuits are stocked worldwide — Cleanline Surf, Surfride, REI, Wetsuit Wearhouse, and O'Neill's own e-commerce all carry the range. The brand is now owned by La Jolla Group in the US and has separate distribution in Europe and Australia, but product design is still centered around the Santa Cruz surf market.

FAQ
Which O'Neill wetsuit should I buy?
For cold water (below 55°F), the Psycho Tech 4/3 or Hyperfreak Fire 4/3 are the two most-recommended suits — the Psycho Tech is warmer and stretchier, the Hyperfreak Fire is $100–150 cheaper. For temperate water (55–65°F), the Hyperfreak 3/2 is the default recommendation. For warm water and entry-level buyers, the Reactor II 3/2 is the value pick.
What is TechnoButter 4 neoprene?
TechnoButter 4 is O'Neill's flagship neoprene — a super-stretchy foam that keeps warm-water flexibility even at 4mm thickness. It's the material inside the Psycho Tech and Hyperfreak Fire. Older TechnoButter 3 is used in the Hyperfreak, and standard neoprene in the Reactor II.
How long do O'Neill wetsuits last?
With regular use (2–4 surfs a week) and proper rinsing, an O'Neill Psycho Tech typically lasts 2–4 years before the neoprene loses stretch. Entry-level suits like the Reactor II usually last 1–2 years. O'Neill offers warranty on stitching and seam failures for six months on most models.
How does O'Neill compare to Rip Curl or Xcel?
O'Neill, Rip Curl and Xcel are the three most-reviewed premium wetsuit brands in the world. All make comparable-quality flagship suits (Psycho Tech vs. Flashbomb vs. Drylock). The choice usually comes down to fit — bodies are different, and each brand's cut suits different builds. Try in a local shop when possible.
How much do O'Neill wetsuits cost?
New O'Neill wetsuits range from about $200 (Reactor II 3/2) to $600 (Psycho Tech 5/4/3 hooded) in the US. Cold-water 4/3s from the Psycho Tech and Hyperfreak Fire ranges sit around $400–$500.
