O'Neill Reactor-2 1.5mm Front Zip Long Sleeve Jacket - Warm, Flexible

In this review of the O'Neill Reactor-2 1.5mm Front Zip Long Sleeve Jacket the bottom line is simple: it is an ideal entry-level wetsuit jacket for anyone wanting warmth and stretch on a budget. The Reactor-2 balances flexibility and durability, making it a practical choice for surfing, paddle sports, lake activities and casual diving where water temps hover around the high 60s. The front zip and strategic seam placement deliver straightforward on-water performance while the wind-resistant smooth skin adds a measurable layer of insulation and protection.

Key Features

• 1.5mm neoprene construction: Provides a responsive stretch for paddling and mobility while still offering light thermal protection for cooler days on the water.
• Front zip closure: Makes the jacket easy to put on and take off, simplifying transitions between activities like surfing and paddleboarding.
• Strategic seam placement: Reduces chafing and improves fit across the shoulders and chest for longer sessions in the water.
• Wind-resistant smooth skin panels: Add extra insulation and help block wind chill when launching from a beach or boat.
• Hand-cuff stitch sleeve anchor: Keeps sleeves secure during movement so cuffs do not ride up while paddling or diving.
• Value-driven design: Engineered to deliver core wetsuit performance at an entry-level price for multi-sport use.

Who It's For

The Reactor-2 is best for recreational water users who need a versatile, affordable wetsuit jacket for surf sessions, wake sports, snorkeling and brief dives in mild to cool water. It suits those who value comfort and stretch over thick thermal protection and who will benefit from the front zip entry for quick changes.

It is less suitable for extended cold-water diving or technical cold-weather diving where thicker suits and seals are required. Also, those needing a precise long-torso fit should check sizing carefully, as some customers report the large can sit short on long upper bodies.

Pros & Cons

Pros

• Good combination of warmth and flexibility for multiple water sports.
• Wind-resistant smooth skin adds comfort during launches and on windy days.
• Durable construction and strategic seams reduce wear in high movement areas.
• Easy front-zip entry speeds on and off between activities.

Cons

• Zipper quality and ease of use are mixed in customer reports; some find it stiff or awkward to close.
• Sizing can be inconsistent for long-torso builds, so measuring against the size guide is recommended.
