The O’Neill Reactor-2 2mm Back Zip S/S Spring is a men’s wetsuit designed for regular sessions in warm water. It’s a solid choice for water sports enthusiasts practicing windsurfing, kitesurfing, or surfing who are looking for a simple, functional wetsuit for summer conditions.
The wetsuit is made from UltraFlex neoprene, offering a good balance of stretch and durability. The material allows natural movement on the board and performs well during dynamic riding and maneuvering.
Strategic seam placement helps reduce material stress and improves overall comfort. Flatlock stitched seams are breathable, making this wetsuit well suited for warmer conditions where ventilation and quick drying are important.
The back zip closure allows for quick and easy entry, while the adjustable single-seal collar improves fit around the neck and helps limit water flushing. A small but practical key pocket adds convenience during sessions at the spot.
The Spring-style cut with short sleeves and knee-length legs is ideal for days when a full wetsuit feels too warm, but you still want protection against cooling and abrasion.
