10 Best Triathlon Wetsuits 2025 in the United States

The Dark Lightning Full Body Wetsuit is made from 3/2mm premium stretch neoprene, providing a good balance of warmth and flexibility for water temperatures around 58–68°F. This thickness is suitable for mild to cool conditions, making it a solid choice for recreational swimmers, surfers, and triathletes training in those environments. Its high-elasticity neoprene helps maintain unrestricted movement, an important feature for swimming and paddling activities.

The fit has been improved based on customer feedback, and the availability of an updated size chart helps users find a comfortable match. The wetsuit features a classic back zipper with an extended leash, making it easy to put on and take off, even for beginners. However, this back zipper design might allow some water entry compared to front or chest zippers commonly preferred in higher-end triathlon wetsuits for reduced drag and better sealing. The seams appear standard, offering decent durability but may not be as smooth or glued for maximum water resistance and comfort seen in more expensive models. The plain black design keeps it versatile and understated, appealing to those who want simplicity over flashy colors.

This wetsuit offers good buoyancy and warmth for its thickness but might not be ideal for very cold water or serious competitive triathletes seeking specialized features like ultra-flexible panels or advanced seam technology. It fits well for recreational and entry-level triathlon or multisport users seeking an affordable and comfortable option in moderate water temperatures.

The Synergy Endorphin Men's Full Sleeve Triathlon Wetsuit is designed for triathletes of all levels, offering a great balance of performance and comfort. Made from high-quality Yamamoto #39 neoprene with a silicone coating, it provides excellent flexibility—claimed to stretch up to 680%, which helps with free arm movement during swimming. The wetsuit’s thickness varies from 5mm in the core for maximum buoyancy (helping you float higher and swim more efficiently) to thinner 2mm panels on the arms and shoulders for better mobility. This makes it suitable for colder water while still allowing a good range of motion. The fit is enhanced by a wide size range, aimed at securing a snug but comfortable feel, which is crucial in keeping water entry minimal and improving swim speed.

The YKK internal zipper is corrosion-resistant and designed to reduce drag, which is a nice touch for serious swimmers. The soft, low neck design adds comfort without restricting movement. Since it’s a 5mm thick wetsuit, it might feel a bit bulkier or warmer than thinner options if used in temperate or warm water. While it has many features for flexibility and buoyancy, some users might find pricing or availability a consideration as it’s a specialized product. The 2-year warranty provides reassurance for durability. This wetsuit is ideal for triathletes seeking a reliable, high-buoyancy wetsuit that balances warmth, flexibility, and speed, especially in colder open-water conditions.

The Zoot Women’s Kona 2.0 wetsuit is designed as a versatile, long-sleeve suit primarily for triathlons but also suitable for swimming, diving, and snorkeling. Made from 2mm Yamamoto neoprene, it offers good flexibility and a comfortable fit, especially with its stretch panels and 100% nylon lining that help with easy entry and exit. The AQUAlift buoyancy technology is a plus, helping swimmers maintain a better position in the water, which is important during triathlons. The GLIDEflex panels on the chest expand with your breathing, providing better breathability than many traditional wetsuits, enhancing comfort on longer swims.

The dorsal zipper at the back is designed for smooth opening and closing, although rear zippers may sometimes be less convenient than front zips for self-assistance. At 2mm thickness, the suit balances warmth and flexibility but may not be ideal for very cold water conditions. While the wetsuit is tailored for women and offers an X-Large size, the fit could vary depending on body shape, so trying it on or checking sizing carefully is recommended. The seams appear well-constructed, contributing to durability without sacrificing movement.

This wetsuit is well suited for women looking for a comfortable, performance-oriented option for triathlons and various water sports, especially in moderate water temperatures.
