Prolimit Mercury 4/3 — Ultimate Warmth, Eco Innovation

The Prolimit Mercury 4/3 is built for riders who won’t compromise on warmth, flexibility, or sustainability. As the most versatile wetsuit in the Prolimit lineup, the Mercury delivers proven performance powered by cutting-edge Thermal Rebound Technology, giving you unmatched comfort in cold-water sessions.

Maximum Warmth, Intelligent Design

At its core, the Mercury features an advanced Thermal Rebound layer placed between the NaturePrene2® outer shell and Zodiac inner lining. This reflective barrier traps and retains body heat while shielding you from wind chill, ensuring consistent warmth in challenging conditions.

With 4mm NaturePrene2® panels around the body for superior insulation and 3mm panels in the arms and legs for freedom of movement, the Mercury 4/3 strikes the perfect balance of warmth and flexibility.

Eco-Friendly and High-Performance

Made from FSC-certified NaturePrene2®, the Mercury is 100% neoprene-free — lighter, more elastic, and environmentally conscious. The Neolight Heather 550+ outer lining adds both performance and sophistication, offering a smooth, soft, and durable finish that enhances stretch and comfort. The subtle two-tone color scheme highlights the use of Thermal Rebound zones, emphasizing both style and function.

Inside, the Velvet Quick-Dry and Zodiac2 Plush linings deliver a soft, warm, and fast-drying feel — keeping you comfortable before, during, and after every session.

Engineered for Durability and Ease

A YKK Freezip front entry allows for quick, easy access and a secure fit. Triple-glued seams are sealed with a liquid rubber coating, providing a watertight, flexible, and long-lasting construction built to perform in demanding conditions.
