10 Best Kids Wetsuits 2025 in the United States

The O'Neill Youth Reactor-2 3:2mm Back Zip Full Wetsuit is a solid choice for kids starting out in water sports like surfing, paddleboarding, and kayaking. Made from ultra-stretch neoprene, it offers good flexibility and comfort, which helps kids move freely without feeling restricted. The 3:2mm thickness strikes a nice balance, providing lightweight warmth for most cool water conditions without being too bulky. Its back zip design makes it easy to put on and take off, while the water-resistant zipper helps keep out cold water.

The seamless paddle zones minimize irritation around the arms and shoulders, making it especially comfortable for active kids who will be paddling a lot. The wind-resistant smoothskin material adds extra insulation, which is great for chilly days at the lake or beach. The fit is tailored for kids around 4'9" to 5'1" tall, so checking measurements is important for a snug feel. While it's perfect for entry-level use and various water activities, it may not be warm enough for very cold water or extended exposure.

This lightweight, flexible wetsuit balances ease of use and comfort, making it a practical pick for young water enthusiasts.

The Seaskin Kids Wetsuit is designed for young water sport enthusiasts, offering options for both a 2mm shorty wetsuit with a front zipper and a 3mm full wetsuit with a back zipper. Made from 90% neoprene and 10% nylon, the wetsuit is designed to keep kids warm in the water, protect against marine irritants, and offer UV protection. The neoprene material provides buoyancy, which can help improve swimming ability, while the flatlock seams and anatomical cut provide comfort and flexibility.

The long front zipper on the shorty suit makes it easy for kids to put on and take off. This wetsuit is suitable for a variety of water sports, including swimming, surfing, and diving. However, some users might find the fit to be an issue, especially if their child is between sizes. Additionally, while the neoprene material offers warmth and protection, it might not be as durable as higher-end materials used in more expensive wetsuits.

The O'NEILL Unisex Child Youth Reactor-2 wetsuit is designed for kids who enjoy activities like surfing, diving, and paddle sports. One of its strong points is the ultra-stretch neoprene material, which offers a great balance of softness and flexibility, allowing for comfortable movement in the water. The 3/2mm thickness provides sufficient insulation for cooler conditions, making it suitable for various climates and water temperatures. Its back zip system is another highlight, making it easy for kids to put on and take off, which can be a big help for parents too. Plus, the wind-resistant smoothskin layer adds an extra level of warmth against chilly winds, enhancing the experience during beach days or lake activities.

On the downside, while the wetsuit is a fantastic entry-level option, it may not provide the same level of durability as higher-end models, especially with more rigorous use. The fit, particularly the 16 size (which fits a chest measurement of 33"-35" and waist of 27.9"-29.9"), might be limiting for some children who fall outside these measurements, meaning you’ll need to ensure a good fit for optimal performance. Additionally, the minimal seam placement, while enhancing comfort and flexibility, can sometimes lead to concerns about water resistance compared to wetsuits with more reinforced seams.

The O'NEILL Reactor-2 is a solid choice for kids venturing into water sports, offering comfort and ease of use at a reasonable price point. Just be mindful of the fit and potential durability concerns based on usage frequency.
