ThruDark Technologies

Designed for pinnacle performance.

Moisture Wicking

Micro Ventilation

Body-mapped to target critical areas of perspiration, micro ventilation technology helps wick moisture away from the body’s core without compromising on insulation. Utilising advanced engineering techniques for maximum performance output with minimal loss of functional performance. Micro-ventilation will help sweat escape, without allowing unwanted water ingress from the elements.

Performance

Compression Technology

A technical fabric blend typically worn by athletes to aid muscle recovery and improve circulation when worn. Compression technology improves performance during periods of dynamic activity by reducing muscle soreness and preventing strains. It also enhances oxygenation helping to minimise numbness and swelling sometimes associated with long term physical exertion.

Unparalleled thermal regulation

Merino X Polyamide

Merino wool offers unparalleled thermal regulation and odour resistance compared with other natural fibres and comes at a very low carry weight. Its fine structure improves wearability next to skin and it can absorb as much as 30% of its weight in moisture without feeling wet, keeping you dry even in dire conditions. The addition of hydrophobic Polyamide lends additional synthetic water resistance and bolsters anti-pilling characteristics.
