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 Synergy Triathlon Wetsuit 3/2mm is designed for triathletes of all levels, including Ironman competitors, making it a solid option if you want a reliable, race-approved wetsuit. Made from neoprene with a smoothskin silicone-coated surface, it offers good buoyancy thanks to the thicker 3mm panels on the core and slightly thinner 2mm panels on the legs and back. This thickness combination helps you float better and swim faster while maintaining flexibility, which is important for comfortable movement during your race. The full sleeve design and wide range of sizes ensure a snug fit, which is crucial to prevent water from seeping in and slowing you down.

The wetsuit features a high-quality YKK zipper inside to reduce drag and improve durability, plus a soft neck that feels comfortable and avoids irritation. It is a reasonably lightweight wetsuit at about 1.38 kilograms, which helps reduce fatigue over long swims. The one-year warranty adds peace of mind for your investment.

For most triathletes seeking a flexible, buoyant wetsuit that balances performance and comfort without breaking the bank, the Synergy Volution Full Sleeve wetsuit presents a dependable choice.
