ONeill Reactor-2 1.5mm Front Zip Sleeveless Wetsuit

The O'Neill Reactor-2 1.5mm Front Zip Sleeveless Wetsuit is built for paddlers who want warmth around the core and legs without loading up the shoulders. For SUP, kayak and other paddle-led sessions, that sleeveless layout often feels far more natural than a full steamer.

Within the O'Neill range, Reactor-2 sits at the affordable, easy-going end. It is the suit we usually point first-time buyers, occasional users and growing families towards when they want reliable comfort without jumping straight into premium pricing.

Why we recommend it

• Lighter neoprene feel that keeps the chill and wind off without feeling overbuilt for warm-weather sessions.
• Sleeveless cut leaves your shoulders free, which is especially nice for SUP, paddling and any session with a lot of upper-body movement.
• Front zip access keeps the suit easier to step into while still feeling cleaner and neater than a traditional back zip.
• Value-led Reactor-2 positioning makes this a sensible buy for newer riders, occasional use and anyone keeping an eye on budget.

FAQs

This style is aimed at warm-weather use, paddling freedom and lighter insulation rather than full winter warmth.

Chest and front zip designs usually feel more secure and performance-led on the water. They tend to flush less and leave the shoulders feeling freer, although they can take a little longer to get into.

Choose Reactor-2 if you want dependable O'Neill quality at a sensible price and you are not trying to buy the most technical suit in the range. If you are on the water more regularly, Epic or above is where the next step starts.
