Reactor II by O’Neill is one of the most popular surf wetsuits on the market. There are so many model variations for everyone out there. It’s a great spring/summer entry-level wetsuit that comes in many different shapes, sizes, and designs.
O’Neill is the oldest wetsuit manufacturers out there – well known for its large range of sizes and models at an affordable price tag. As the Reactor series is originally designed for such high activity-sport as surfing, many people also use it on all sorts of other water-related activities such as snorkeling, swimming, freediving, sailing, kayaking and so on.

- Flatlock stitched – The most popular method of sewn construction. The stitch uses 4 needles and 6 threads and works by overlapping the neoprene panels and sewing them together. It is a strong stitch and is very comfortable because it is flat, but it is not a sealed seam so it is not intended for extremely cold conditions.
- Strategic seamless paddle zones An ergonomic, seamless undersleeve panel that allows for unrestricted motion and eliminates rashing. Flexible and unique design that utilizes minimal seam placement for comfort.
- Krypto knee pads Abrasion resistant, high stretch neoprene panel with ergonomic shaping for comfortable durability. The flexible and unique design utilizes an extended knee pad for added durability.
Anywhere from $70 up to $200
O’Neill Reactor 2 CONS:
- The flatlock stitching lets water come through, but that’s expected to any suit with that type of stitching
- It’s an entry-level summer/springsuit with basic technology and limited thicknesses
Total Score: 4/5
What I personally like the most about the Reactor series is that it features a ton of different sizes for everyone – from toddlers, boys&girls, and up to men with a beer barrel. After reading a ton of reviews, most people find it very comfortable and well-fitting.
Key Factors When Choosing A Wetsuit
- TYPE – Determine which type of wetsuit do you need: A top, short sleeve top, or a full suit.
- THICKNESS – Choose the right thickness for the season.
- SIZE – Make sure you get exactly the right size. When you have to choose between two sizes, weight is more important!
Thickness & activity recommendations
- 1mm – Comfortable for summer use only
Snorkeling, Swimming, Kayaking, Surfing, Stand-Up Paddleboarding, Kiteboarding
- 1.5mm – Warm weather activities
Snorkeling, Swimming, Kayaking, Surfing, Stand-Up Paddleboarding, Kiteboarding, Sailing
- 2mm – Summer suit. An ideal choice for those in-between weathers where 1mm would be too cold and 3mm too restrictive. Perfect for freediving as it’s not that thick and floaty.
Snorkeling, Swimming, Kayaking, Surfing, Stand-Up Paddleboarding, Kiteboarding, Freediving, Diving, Sailing
- 3/2 – Springsuit. Great for those late spring/early autumn frisky sessions
