Arctic X One Piece

Manufacturer Fourth Element

If you're serious about cold-water diving, a one-piece undersuit is hard to beat — and the Fourth Element Arctic X One Piece is  head-to-toe coverage, no gaps between jacket and leggings, and no cold water finding its way to your lower back mid-dive. It's the kind of kit that makes you wonder why you ever bothered with separates.

Built from recycled materials with a DWR water-repellent outer shell and a warm fleece lining, the Arctic X One Piece delivers serious thermal performance without the bulk.

The full-length two-way zip runs the length of the front, making it straightforward to get on and off even in a cramped dive boat — and if you need a pee valve fitted, it's ready for one straight out of the box. Articulated sleeves and knees, combined with 4-way stretch fabric, mean the suit moves with you in any position, especially in horizontal trim where fit really counts.

Thumb loops and single-layer foot stirrups keep everything in place while you're pulling on your drysuit, and the low-bulk ankle design means no fighting with excess fabric around your feet. Pockets give you quick access to small essentials, and subtle reflective detailing adds low-light visibility when you need it. Certified to Global Recycled Standard (GRS), Oeko-Tex 100 and Bluesign standards, plastic-free packaged, and machine washable. Available in both regular and short leg lengths.
