ARC 5/4mm ADULT Outdoor Centre/Coasteering Unisex Back Zip Wetsuit

The Circle One ARC centre wetsuit is a high-performance, all-season solution engineered specifically for the rigorous demands of surf schools, outdoor centres, and professional adventure operators. Built to endure continuous use in challenging environments, the ARC has become the wetsuit of choice for a wide range of water-based activities including coasteering, canyoning, white water rafting, surfing, kayaking, and paddlesports.

Trusted by leading outdoor centres and the Royal Marines, the ARC is designed with durability and functionality at its core. Developed through years of collaboration with instructors and activity providers, it incorporates premium-grade materials and advanced construction techniques to deliver long-lasting performance.

Key technical features include double Glued and Blind-Stitched seams, a reinforced lumbar and seat area, abrasion-resistant forearms, and durable core-tex knee panels. The unique diagonal back zip configuration is engineered to reduce stress at the base of the zip while improving upper-body flexibility.

Constructed as a four-season wetsuit, the ARC provides excellent thermal protection with strategically placed neoprene thicknesses: 5mm on the torso for core warmth, 4mm on the legs, and 3mm on the arms and shoulders to enhance mobility. Flexible stretch panels are integrated at critical movement zones — underarms, thighs, lower legs, and back — to ensure unrestricted motion during high-intensity use. The suit’s tailored chest and leg paneling accommodate a unisex fit, providing ergonomic comfort for both male and female users.
