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

The Circle One ARC Centre Wetsuit is a high-performance, four-season wetsuit built for the real-world demands of surf schools, outdoor centres, and professional adventure operators. Engineered to handle continuous use in tough environments, it’s ideal for high-wear 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 uses premium-grade materials and proven construction to deliver long-lasting performance season after season.

Why the ARC Works for Centres

The ARC is built to reduce common failure points in hard-working centre wetsuits. It features double Glued & Blind-Stitched (GBS) seams, reinforced high-wear zones, and a diagonal back zip designed to reduce stress at the base of the zip while improving upper-body flexibility.

Warmth + Mobility (5/4/3mm)

As a true all-season wetsuit, the ARC delivers dependable thermal protection with strategically placed neoprene thickness: 5mm torso for core warmth, 4mm legs for heat retention, and 3mm arms/shoulders to maximise paddling and mobility. Flexible stretch panels are placed at key movement zones (underarms, thighs, lower legs, and back) to keep motion unrestricted during high-intensity use.

The tailored chest and leg paneling is designed for a unisex fit, offering ergonomic comfort for both male and female users—ideal for centre stock where multiple people may use the same size range.
