O'Neill Men's Reactor II 3/2mm Back Zip Full Wetsuit - Value

Our review of the O'Neill Men's Reactor II 3/2mm Back Zip Full Wetsuit finds it is a practical, entry-level choice for anyone needing a warm, flexible suit without a high price tag. The single biggest reason to buy is the combination of ultra stretch neoprene and a backzip system that together deliver notably easy entry and exit with strong mobility in the water. For casual surfers, paddle sport enthusiasts, and weekend divers who want reliable warmth and comfort, this wetsuit balances performance and value.

Key Features

• Backzip System: The backzip offers straightforward entry and exit while forming a water tight seal that helps retain warmth during sessions.
• Ultra Stretch Neoprene: The premium neoprene provides a soft feel and increased flexibility so paddling and turning feel less restrictive.
• Seamless Paddle Zones: Minimal seam placement across the shoulders and chest improves comfort and reduces chafing during extended paddling.
• Wind-Resistant Smoothskin: Smoothskin panels add insulation and block chill from wind on exposed areas, extending usable conditions.
• Value-Driven Design: The Reactor II is engineered to mix durability and stretch so buyers get performance features without a premium price.

Who It's For

The Reactor II is best for entry-level to intermediate water users: surfers working through progression, paddleboarders, and divers who need a versatile full wetsuit for cool to mildly cold water. The 3/2mm thickness suits temperate conditions and late spring to early fall use in many regions.

Those who should look elsewhere include cold-water specialists who need thicker insulation, or technical divers requiring drysuit-level seals. Also, if zipper longevity is a top concern based on heavy daily use, a suit with reinforced zip hardware or chest-zip access might be preferable.
