O'Neill Men's Reactor-2 1.5mm Front Zip Long Sleeve Jacket - Entry

Our review of the O'Neill Men's Reactor-2 1.5mm Front Zip Long Sleeve Jacket finds it best suited for casual surfers, paddle-sport enthusiasts, and beachgoers who need a versatile, value-driven wetsuit top. The single biggest reason to buy is its blend of stretch and wind-resistant insulation: the ultra stretch neoprene offers a comfortable fit and freedom of movement while the smooth skin panels block chill on breezy days. In short, it performs like a more expensive piece in many common water conditions without demanding a large investment.

Key Features

• Front zip closure: provides easy entry and exit with a water tight seal while keeping the jacket simple to use before and after sessions.
• Ultra stretch neoprene: the soft premium material improves mobility and comfort so paddling and surf maneuvers feel less restricted.
• Seamless paddle zones: minimal seam placement reduces chafe and enhances reach for longer, more comfortable strokes.
• Wind-resistant smooth skin: extra insulation at the surface blocks wind chill for better warmth on cool lake or beach days.
• Value-driven design: engineered for performance without premium pricing, making it a practical choice for entry-level buyers.

Who It's For

The Reactor-2 is ideal for recreational surfers, divers doing short dives, paddleboarders, and anyone needing extra insulation for beach and lake activities. It fits people who want a reliable, flexible wetsuit top that balances warmth and range of motion without the complexity of a high-end full suit.

Those needing thick, cold-water protection for extended dives or professional use should look at heavier, purpose-built suits; likewise, advanced surfers who demand the highest seam technology and thicker neoprene year-round may prefer premium models with more specialized features.

Frequently Asked Questions

Is this jacket warm enough for cool water?
The 1.5mm thickness and smooth skin panels provide light insulation and wind protection but are best for mild or transitional temperatures rather than very cold water.

How easy is it to get on and off?
The front zip closure is designed for easy entry and exit while maintaining a snug, water-resistant fit when zipped.
