🔥 Introducing the NEW Fourth Element Arctic X Thermal Undersuit 🔥
The Arctic undersuit has long been the benchmark for thermal performance beneath a drysuit, trusted by divers around the world in some of the most demanding conditions. Now, Fourth Element has taken everything divers already love about the Arctic and refined it even further.
The new Arctic X is designed for divers who demand streamlined performance, delivering exceptional warmth, comfort and protection without unnecessary bulk. Its ergonomic cut, articulated sleeves and knees, and stretch fabric provide outstanding freedom of movement, whether you're finning through a wreck or maintaining perfect horizontal trim.
Constructed using recycled materials and finished with a durable water-repellent coating, the Arctic X helps keep you warm, dry and focused throughout every dive. Thoughtful details such as the full-length two-way zip, thumb loops, foot stirrups, low-profile ankles, practical pockets and reflective accents make gearing up easier and diving more comfortable from start to finish.
For divers who refuse to compromise on warmth, mobility or performance, the Arctic X is ready for your next cold-water adventure.
