7 Best Long John Wetsuits 2026 in the United States

The O'Neill Women's Reactor-2 3/2mm Back Zip Full Wetsuit is designed as an entry-level wetsuit suitable for various water activities like surfing and diving. With a thickness of 3/2mm, it offers decent insulation for mildly cold waters. The wetsuit is made from ultra-stretch neoprene, which is known for its flexibility and comfort. This material helps improve performance by allowing greater freedom of movement.

The seamless paddle zones enhance this mobility by reducing seam placement, thereby minimizing discomfort during paddling or swimming. Additionally, the wind-resistant smoothskin provides extra insulation against cold winds, which is beneficial in keeping the wearer warmer in cooler conditions. The backzip entry system is user-friendly, simplifying the process of putting the wetsuit on and taking it off, while maintaining a water-resistant closure to minimize water entry.

The fit is tailored for women, with specific size dimensions ensuring better comfort and performance during activities. Some users might find the sizing a bit tricky as it is specified in Short format (10S), which is suitable for individuals within a specific height and weight range. This wetsuit ranks well in its category, and its strengths lie in its material quality, comfort, and ease of use. However, it might not be the best choice for those needing extremely thick wetsuits for very cold water or those preferring chest zip systems.

The Zone3 Men's Agile wetsuit is designed with a smart mix of neoprene thicknesses—2mm in the shoulders for flexibility, 3mm and 4mm in other areas for warmth and support—helping swimmers stay comfortable and conserve energy. The glued and blind-stitched seams keep water out and add comfort, which is important for longer swims. Fit-wise, this wetsuit uses a balanced profile with core panels on the upper legs to reduce drag, making it easier to glide through the water. It also features a full-length zipper with Slimline Pro Speed Cuffs, which makes putting it on and taking it off faster and less frustrating. The Speedflo waterproof coating helps reduce drag further, improving swimming speed. High-visibility panels are a useful safety feature if you’re swimming in open water.

One downside is that while the suit aims for a snug fit, some users might find certain sizes a bit tricky to get just right, as wetsuit fit can vary by body shape. Additionally, while the material and seam construction are solid for the price, it’s not the thickest or most premium wetsuit on the market, so in extremely cold water, it might not provide the highest warmth.

This wetsuit is a strong option for triathletes or regular swimmers seeking a flexible, energy-saving suit with easy entry and decent warmth.

The O'Neill Reactor-2 Women's 1.5mm Sleeveless Full wetsuit is designed to balance flexibility and durability, making it a good choice for warmer water or active paddling. With a thickness of 1.5mm, it provides light insulation, which is ideal if you want some protection without feeling too warm or restricted. The material features a combination of wind-proof smooth skin on the outside and ultra-flex neoprene that allows ease of movement. This makes it comfortable for sports that require arm mobility, especially with its sleeveless design and seamless paddle zones that reduce chafing. The flatlock stitched seams are breathable but not fully waterproof, meaning it’s better suited for mild conditions rather than cold or rough waters. The front zipper with a Super Seal neck is an easy entry system that helps to keep water out, though some might prefer a back zip for easier access.

The fit is tailored for women, and the size 12 matches chest and waist measurements that should fit well for people within those dimensions, offering a snug but flexible fit. Weighing just 14.4 ounces, it’s lightweight and easy to wear for extended periods. On the downside, the sleeveless design might not provide enough warmth for colder conditions, and the flatlock seams, while comfortable, won’t keep water out as well as glued or taped seams. This wetsuit is ideal for casual water activities in temperate climates where flexibility and light protection are key.
