BRYNJE: Antarctic Pro Jacket

The Brynje Antarctic Pro Jacket is an expedition-grade insulated jacket built for extreme cold, professional use, and long days outdoors. Using the same proven dual-layer principle as Brynje’s Arctic Collection—but with a heavier merino wool outer layer—this jacket delivers exceptional warmth, moisture control, and durability.

A Super Thermo mesh inner layer actively regulates body temperature, keeps moisture off the skin, and provides additional insulation. A soft middle layer with a windstopper panel in the front adds wind protection where it’s needed most, without sacrificing breathability. The result is a jacket that performs reliably during high activity in severe cold.

Designed to function as a midlayer in extreme temperatures or as an outer layer in dry conditions, the Antarctic Pro Jacket meets the high standards required for expedition use while maintaining the comfort and versatility of everyday wear. This Pro version is specifically adapted for professional users, including hunters, law enforcement, and rescue services.

For optimal performance, Brynje recommends wearing Super Thermo mesh next to the skin. On particularly cold days, a Classic merino wool midlayer can be added underneath.
