Its Astro Thermal liner adds warmth, making it suitable for colder temperatures.

The wetsuit features a 5mm thick core buoyancy panel, 3mm lower legs and back, and 2mm arms and shoulders, providing maximum buoyancy which is particularly beneficial in cold water, helping you float higher and move faster, thus saving energy during a triathlon.

The YKK anti-corrode internal zipper helps reduce drag, further enhancing your swimming efficiency.

Additionally, the soft low neck with smoothskin ensures comfort, preventing chafing or discomfort around the neck area. However, the wetsuit's thickness may be a bit much for warmer waters, and its high buoyancy might not be as beneficial for more experienced swimmers who prefer less buoyancy. The 2-year warranty provides peace of mind, though it requires product registration and only applies to the original owner. This wetsuit is well-regarded and offers excellent features tailored for triathletes, particularly those competing in cold water events.

The Orca Men's Athlex Float Wetsuit is designed specifically for triathlon swimmers looking for a balance between buoyancy, flexibility, and comfort.

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.
