The Fourth Element Men's Xenos Arc 5mm Wetsuit delivers versatile thermal protection for divers working across a range of water temperatures. Built with 85% natural rubber and a dual-layer Thermoflex torso lining, it balances warmth and flexibility for year-round diving in temperate waters and multi-day dive trips.
Product Overview
Designed for divers who need reliable protection across a broad temperature range, the Xenos Arc 5mm handles everything from temperate reef systems to cooler seasonal waters. The low-friction arm and leg lining dries fast between dives and makes donning effortless, while ultra-stretch neoprene moves naturally through every fin cycle.
Flush protection comes from 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 keep water from seeping through at the joints, maintaining warmth across long dive days.
Abrasion-resistant knee pads stand up to boat decks and rocky entries, and the cut-away back heel notch simplifies getting in and out. For year-round divers looking for a versatile wetsuit that bridges the gap between tropical and cold-water exposure protection, the 5mm Xenos Arc is a strong all-rounder.
