O'Neill Women's Reactor-2 3/2mm Back Zip Full Wetsuit - Flexible

In this review the O'Neill Women's Reactor-2 3/2mm Back Zip Full Wetsuit is evaluated for travelers, casual surfers, and warm-water divers who need lightweight thermal protection without bulk. The bottom line: it delivers a great balance of flexibility and sun/sting protection thanks to a 2mm/3mm panel layout and lightweight FluidFoam insulation, making it ideal for summer sessions and tropical trips where water is warm but heat loss still matters. The suit's combination of seamless paddle zones and a SuperSeal collar makes it especially comfortable for active paddling and long hours in the water.

Key Features

• 2mm FluidFlex shoulders and sleeves: allow unrestricted arm movement for paddling and surfing while maintaining a close fit to reduce water entry.
• 3mm FluidFoam body: provides lightweight warmth across the torso to slow heat loss in warm-to-temperate waters without feeling bulky.
• Seamless paddle zones: remove chafe points on the shoulders so longer sessions remain comfortable and free of irritation.
• SuperSeal collar and DL single seal neck closure: form a snug, adjustable barrier at the neck to minimize flushing and keep warmth in.
• Wind resistant smoothskin chest and back: reduce wind chill on the torso when entering or exiting the water and during breezy beach days.
• Back zip with hidden key pocket: makes the suit easy to get on and off while providing a convenient place for a small key.

Who It's For

The Reactor-2 is aimed at women who spend time in warm to mildly cool water and want a low-profile suit that still offers protection from sun, stings, and abrasion. It works well for surfers, stand-up paddlers, snorkelers, and vacationers who need a durable, comfortable full suit that does not sacrifice range of motion.

Those who need maximum cold-water insulation, thick neoprene for very cold climates, or specialized drysuit features should look elsewhere; this suit is optimized for flexibility and light warmth rather than heavy thermal protection.

Pros & Cons

Pros

• Flexible 2mm panels on the arms keep mobility high for paddling and surfing.
• Lightweight 3mm FluidFoam torso balances warmth with low weight and quick drying.
• SuperSeal collar and wind resistant smoothskin panels reduce flushing and wind chill.
• Flatlock stitching produces breathable, non-chafing seams for comfort in warm conditions.

Cons

• At 3/2mm thickness the suit is not designed for prolonged use in cold water or for divers needing thick thermal protection.
