Fourth Element Men's X-Core Vest

Fourth Element Men's X-Core Vest

Boost warmth where it matters most. The X-Core Vest adds exceptional core insulation beneath your drysuit undergarment, with a sleeveless design that keeps your shoulders and arms free to move.

Key Features & Benefits

  • Exceptional core warmth: Heavyweight insulation adds thermal protection around your torso for greater comfort on colder dives.

  • Enhance your layering system: Wear beneath an Arctic, Halo A°R or another drysuit undergarment for additional warmth.

  • Flexible layering: Performs best over a lightweight J2 or Xerotherm base layer, but can also be worn directly against your skin.

  • Freedom to move: The sleeveless design limits extra bulk around your shoulders and arms while minimising its impact on buoyancy.

  • Snug, flexible fit: Four-way stretch fabric and a long body help maintain coverage and minimise cold spots.

  • Extra chest protection: An additional chest panel helps reduce the rush of cold air from your drysuit inlet valve while adding insulation.

  • Stay drier and warmer: Fast-wicking fabric moves perspiration towards the outer surface to support thermal comfort.

  • Lasting freshness: Odour-resistant fabric helps maintain freshness during wear.

  • Recycled materials: Contains 76% recycled polyester, with Polartec® Power Stretch® fabric certified to bluesign® and OEKO-TEX® standards.

  • Easy care: Machine washable for straightforward maintenance.

Fabric & Care

  • Composition: 92% polyester, 8% elastane, including 76% recycled polyester.
  • Machine washable.
