O'Neill Youth Reactor-2 3/2mm Back Zip Full Wetsuit - Youth

In this review of the O'Neill Youth Reactor-2 3/2mm Back Zip Full Wetsuit we look at who will get the most from a stretch neoprene fullsuit designed for cooler water play. The bottom line: this is a value-driven, entry-level kids wetsuit that prioritizes warmth, flexibility and easy on/off with a backzip - ideal for toddlers and young children who need dependable insulation and freedom of movement during surf lessons, paddle sessions or beach days.

Key Features

• 3/2mm FluidFlex neoprene: Provides a balance of warmth and flexibility suitable for water temperatures roughly 58-68F, keeping small riders comfortable without restricting movement.
• Backzip YKK closure: Offers easy entry and exit for parents dressing wriggly kids while the water resistant zipper helps reduce flushing and retain warmth.
• Seamless paddle zones: Minimal seam placement across the shoulders and arms increases mobility for paddling and swimming without chafing.
• Smoothskin wind-resistant panels: Added insulation on the collar and torso reduces wind chill and improves warmth when out of the water.
• Ultra stretch, soft feel: The premium-feeling neoprene has a soft hand and stretch that elevates comfort and lets children move naturally while learning skills.
• Hidden key pocket and adjustable collar: Small practical touches like a key pocket and a single super seal collar increase convenience and help limit water entry.

Who It's For

The Reactor-2 full wetsuit is aimed at parents buying their first real wetsuit for toddlers or young children who need a warm, flexible suit for surf lessons, lake days, paddle sports and general cold-water play. Its 3/2mm thickness and smoothskin panels make it suitable for transitional seasons and cooler summer water where extra insulation matters.

Families looking for technical race-fit performance or heavyweight insulation for very cold water should look elsewhere; this suit is built as an entry-level, value-oriented option that emphasizes stretch and ease of use rather than specialized thermal systems or adult sizing precision.
