Fourth Element Women's Halo A°R

Fourth Element Women's Halo A°R

Experience exceptional warmth without the bulk. The Halo A°R combines advanced A°RGON™ aerogel insulation with bodymapped protection, delivering a thinner, less buoyant undersuit designed for comfort and freedom of movement.

Key Features & Benefits

  • Advanced aerogel insulation: A°RGON™ uses technology originally developed for space exploration and cryogenics to deliver exceptional thermal protection.

  • Warmth without bulk: A compression-resistant insulation matrix provides high thermal performance in a thinner, less buoyant design.

  • Bodymapped protection: A°RGON™ covers the body from shoulders to knees, with additional protection in other critical areas while preserving mobility.

  • Refined through thermal imaging: Prototypes were assessed using thermal imaging cameras to identify heat loss and improve insulation placement.

  • Optimised for horizontal trim: An offset chest zip and insulating baffles help minimise heat loss from your torso in your diving position.

  • Protection between dives: A wind- and water-repellent outer layer adds comfort when exposed above the surface.

  • Move freely: All-way stretch fabric provides a snug, flexible fit without unnecessary restriction.

  • Easier donning: Comfortable thumb loops and foot stirrups help keep sleeves and legs in place while putting on your drysuit.

  • P-valve ready: A zipped right-hand pocket includes a second internal zip, providing access for routing and adjusting your p-valve tubing.

  • Comfort throughout the day: Designed for extended wear, from gearing up to surface intervals.

  • Easy care: Machine washable for straightforward maintenance.

Fabric & Care

  • Outer: 83% polyester, 13% PU, 4% elastane.
  • Insulation: A°RGON™.
  • Inner: 68% polyester, 32% recycled S.Café® polyester.
  • Machine washable.
