SIEGE BASE LAYER
The battle-tested base layer, insulated and hard wearing enough to be worn on its own or as part of a layering system.
Developed with Polartec® Power Grid, a geometric construction fabric that enhances moisture evaporation and supports thermal regulation. The grid design creates open air channels that improve breathability and reduce fabric mass. With a high neck collar and integrated thumb loops for increased cold weather protection.
When under Siege from the cold, this first line of defense will repel any onslaught.
