O'Neill Reactor-2 1.5mm Front Zip Long Sleeve Jacket - Stretch

Our review of the O'Neill Reactor-2 1.5mm Front Zip Long Sleeve Jacket finds it best suited to casual surfers, paddle sport enthusiasts, and lake users who want a comfortable, entry-level wetsuit top with good warmth and mobility. The biggest reason to buy is the combination of ultra-stretch neoprene and a front zip that balances easy entry with a snug, water-resistant fit, delivering reliable insulation for cool conditions without the expense of advanced suit technologies.

Key Features

• Front zip closure: The zipper closure provides straightforward entry and exit while maintaining a secure fit to limit flushing and heat loss.
• Ultra stretch neoprene: The soft premium material improves freedom of movement and reduces fatigue during paddling or long surf sessions.
• Seamless paddle zones: Minimal seam placement across the shoulders enhances comfort and prevents chafing for extended time on the water.
• Wind-resistant smooth skin: Smooth skin panels add extra insulation and help block wind chill on cool, blustery days.
• Value-driven design: Built and upgraded for durability, this jacket aims to deliver performance features at an accessible price for entry-level users.

Who It's For

This wetsuit jacket is aimed at recreational surfers, divers doing shallow-water or warm-to-cool dives, and anyone who needs a versatile layer for paddleboarding, kayaking, or lake activities. Its 1.5mm thickness and wind-resistant panels make it particularly useful in transitional seasons or cooler mornings when full thermal suits are not required.

Those who need extreme cold-water protection, a full-body wetsuit for technical diving, or premium competition wetsuit features should look elsewhere; the Reactor-2 prioritizes flexibility and value over thick insulation or advanced seam taping needed for prolonged submersion in very cold conditions.

Pros & Cons

Pros

• Comfortable, ultra-stretch neoprene offers strong mobility for paddling and surfing.
• Front zip design simplifies entry and maintains a water-tight seal when closed.
• Seamless paddle zones reduce rubbing and improve shoulder movement during strokes.
• Wind-resistant smooth skin panels add useful insulation against chill.

Cons

• At 1.5mm this is a lighter jacket and not intended for extended exposure in very cold water.
• Entry-level focus means it lacks some high-end seam treatments found on premium suits.

Frequently Asked Questions

Is this jacket good for cold water?

How easy is it to put on and take off?
The front zip closure provides easy entry and exit while offering a snug fit that limits water flushing when zipped.

Does it restrict shoulder movement?
No, the seamless paddle zones and ultra-stretch neoprene are designed to maximize mobility and reduce chafing during paddling and surfing.
