The Fourth Element Men's Xenos Arc 7mm Wetsuit provides serious cold-water protection for divers who refuse to cut sessions short. Built with 85% natural rubber and a dual-layer Thermoflex torso lining, this suit maximizes insulation for extended diving in cooler waters without sacrificing the mobility needed below the surface.
Product Overview
Designed for divers who regularly face cold water, the Xenos Arc 7mm is built to keep core temperature stable through extended bottom times and multi-dive days. The dual-layer Thermoflex torso lining works alongside the thicker neoprene to maximize heat retention, while the extended thermal lining through the arms and legs ensures no zone is left unprotected.
Flush protection comes from Glideskin Hydrolock wrist seals, internal silicone ankle seals, and a Glideskin neck seal that sits comfortably without restricting movement. Triple glued and blindstitched seams prevent cold water from seeping through at the joints, which is critical at lower temperatures.
Abrasion-resistant knee pads handle rough surfaces, and the cut-away back heel notch simplifies getting in and out of a thicker suit. For cold-water divers who need a dependable wetsuit that holds its warmth dive after dive, the 7mm Xenos Arc delivers serious insulation without compromising fit or flexibility.

FAQ
The 7mm thickness is built for cold water diving, generally between 45°F and 65°F (7°C and 18°C). For additional warmth in very cold conditions, it can be paired with compatible base layers.
The Thermoflex thermal lining on the torso adds an insulating layer where heat loss is greatest, helping maintain core temperature across multiple dives without adding unnecessary bulk.
All seams are triple glued and blindstitched, which minimizes water penetration at the joints. Combined with the Glideskin Hydrolock wrist seals, silicone ankle seals, and Glideskin neck seal, flush protection is thorough.
Yes. The ultra-stretch neoprene used throughout the Xenos Arc maintains good range of motion despite the thicker material. The low-friction arm and leg lining also helps the suit move freely during finning and gear handling.
The Xenos Arc is available from X-Small through XX-Large, with Short and Tall options for most sizes. See the size guide above for measurements. If you need help choosing, contact sales@bluewaterphotostore.com.
