10 Best Triathlon Wetsuits 2025 in the United States

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.

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 to meet the needs of triathletes at all levels, including Ironman competitors, as it is USAT approved. Made from hydrodynamic neoprene with a silicone-coated surface, it offers a good balance of buoyancy and flexibility. The 3mm thickness around the core provides extra buoyancy to help you float higher and swim more efficiently, while the 2mm neoprene on the legs and back keeps you flexible for easier movement.

Its full-sleeve design and smoothskin material on both sides reduce water resistance, making swimming feel smoother and less tiring. A standout feature is its high-quality YKK zipper that resists corrosion and is designed to minimize drag as you swim. The wetsuit fits a wide range of sizes, providing many women with a comfortable, snug fit—important for performance and warmth. The soft low neck adds comfort without feeling restrictive.

Some users might find the wetsuit a bit warm in milder water temperatures due to the thickness. It carries a 1-year warranty, which helps protect against early defects. This wetsuit is a solid choice for those seeking a reliable option that supports buoyancy and flexibility for triathlon open water swimming, especially in long races, balancing comfort, performance, and durability.
