10 Best Triathlon Wetsuits 2025 in the United States

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 Orca Men's Athlex Float Wetsuit is designed specifically for triathlon swimmers looking for a balance between buoyancy, flexibility, and comfort. Made from neoprene, it offers good thermal insulation which is enhanced by the Hydrolite inner lining that seals the neck area, helping to keep water out and reduce chafing. This also improves hydrodynamics, making swimming more efficient. The wetsuit features a durable YKK 10 zipper known for its strength and water resistance, so you can expect it to last through many races and training sessions. The fit appears to be snug, especially around the neck, thanks to the Ultimate Seal Collar which helps prevent water from entering, contributing to better warmth and buoyancy.

The long sleeves and quality seams further support durability and comfort in the water. The materials and sealing technologies suggest it’s designed to keep you warm without sacrificing flexibility. This wetsuit suits triathletes who want reliable buoyancy and a comfortable fit while valuing a good seal and durability in their triathlon wetsuit.

The O'Neill Men's Reactor-2 3/2mm Back Zip Full Wetsuit is a strong contender for beginners and value-conscious triathletes. Made from ultra-stretch neoprene, it boasts remarkable flexibility and comfort, essential for various water activities like surfing, diving, or paddle sports. The 3mm thickness provides a good balance of warmth and mobility, making it suitable for moderate temperatures. The fit is designed to accommodate larger frames, ideal for those with a chest size of 40-44 inches and a height around 6 feet, although it’s always best to try it on for personal comfort.

The back-zip system is a user-friendly feature, making the wetsuit easy to put on and take off, with a water-resistant closure to minimize water entry. Buoyancy isn't specifically highlighted, but the 3/2mm neoprene should provide adequate lift in the water. The seamless paddle zones are a notable strength, reducing chafing and allowing for greater arm movement. Additionally, the wind-resistant smoothskin offers extra insulation against the cold, increasing comfort during use.

One potential downside could be the seams, which, though minimal, might not be as durable as fully sealed or taped seams found in higher-end wetsuits. Also, while the back zipper is convenient, front-zip alternatives can sometimes provide a better seal and flexibility around the torso. This wetsuit is best suited for entry-level users and those engaging in a variety of water sports, looking for a reliable and comfortable wetsuit at a reasonable price.
