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 Men's O'Riginal 2mm Back Zip Sleeveless Spring Wetsuit is designed for warmer water conditions where a thinner wetsuit works best. With a 2mm thickness on the body and slightly thinner 1.5mm legs, it offers good flexibility and comfort, making it a solid choice for spring or summer water activities. The neoprene material used is common for wetsuits, providing decent insulation and stretch. The glued and blindstitched seams help keep water out while maintaining durability, which is important for longer use.

This sleeveless style allows for better arm movement, especially useful for paddling or surfing, and the back zipper makes it easier to put on and take off compared to chest-zip wetsuits. The fit is designed to be snug but not overly tight, which helps keep water from entering while allowing freedom of movement.

Being sleeveless, it won’t offer full coverage or warmth for colder water. Also, the back zip can sometimes let in a bit more water compared to chest-zip designs but is often preferred for convenience. For those seeking a wetsuit that balances comfort, flexibility, and reasonable warmth in mild conditions, this O'Neill model is a good pick. It is best suited for active users who want freedom to move their arms easily and don’t need thick insulation.
