The Fourth Element Men's Xenos Arc 3mm Wetsuit brings warm-water comfort to divers who demand more from their exposure protection. Built with 85% natural rubber and a dual-layer Thermoflex torso lining, this suit pairs tropical-ready flexibility with reliable insulation for liveaboards and back-to-back dive days in warm conditions.
Product Overview
Designed for long days in and out of the water, the Xenos Arc 3mm is built for liveaboard trips, warm-water destinations, and back-to-back dive sessions where quick transitions matter. The low-friction arm and leg lining dries fast between dives and makes donning effortless, while ultra-stretch neoprene moves naturally with every fin kick and gear check.
Flush protection is handled through Glideskin Hydrolock wrist seals, internal silicone ankle seals, and a Glideskin neck seal that sits comfortably without restricting head movement. Triple glued and blindstitched seams reinforce the suit's ability to keep water from seeping through at the joints.
Abrasion-resistant knee pads hold up on boat decks and rocky entries, and the cut-away back heel notch simplifies getting in and out. For divers looking for a reliable warm-water wetsuit that performs dive after dive, the Xenos Arc 3mm delivers consistent comfort and thermal protection.
