Men's Reactor-2 2mm Back Zip Short Sleeve Wetsuit - Lightweight Warmth

In this review the Reactor-2 2mm back zip short sleeve wetsuit is presented as a practical, value-driven option for anyone wanting light thermal protection with good mobility. The reviewer finds it best suited to warm to mildly cool water activities where flexibility and easy entry matter most. Overall this wetsuit earns praise for its comfortable fit, stretchy neoprene, and sensible construction that keeps costs down while still delivering performance for surfing, paddleboarding and snorkeling.

Key Features

• Neoprene Rubber: Provides lightweight insulation and enough buoyancy for surface water sports without restricting movement.
• Backzip System: The back zip with water resistant closure makes entry and exit straightforward for most users and helps limit flushing.
• Ultra Stretch Neoprene: Premium soft material increases comfort and freedom of movement during paddling and surf maneuvers.
• Seamless Paddle Zones: Minimal seam placement reduces chafing and improves shoulder mobility for extended paddle sessions.
• Wind-Resistant Smoothskin: Smoothskin panels block wind and add extra insulation on cooler days at the beach or on a kayak.
• Entry-Level Value: Engineered as a value package that balances durability and performance for new to occasional users.

Who It's For

The Reactor-2 is aimed at recreational surfers, stand up paddleboarders, snorkelers and kayakers who need a shorty that fits well and stays comfortable in warm to cool water. Its 2mm thickness and short sleeve design work particularly well for summer surf sessions, tropical snorkeling, and lake outings where full thermal coverage is unnecessary.

Serious cold-water divers or year-round surfers in chilly climates should look for thicker full suits or chest zip designs with heavier insulation. Also, riders who prefer a very rigid, competition-oriented wetsuit may find this suit too soft for high-performance trimming.

Pros & Cons

Pros
