About the Brand

The Engine of the Layering System

Aclima is a Norwegian family-owned textile specialist that has been at the forefront of merino wool innovation since 1939. At Brigantes, we recognise that for the modern warfighter, base layers are not just clothing — they are the foundational engine of a layering system, responsible for thermal regulation and moisture management in the most unforgiving climates.

By maintaining complete control over their European production chain, Aclima delivers wool garments that provide unparalleled comfort, durability, and operational performance.

The Brigantes Partnership

NSPA Contract Holders

Brigantes and Aclima share a deep-seated partnership founded on absolute technical trust and a shared commitment to the science of the layer. Through this close relationship, Brigantes has successfully secured a NATO Support and Procurement Agency (NSPA) contract for the Aclima Woolterry range.

This contract ensures that NATO nations have direct, streamlined access to these life-critical thermal systems, backed by the procurement expertise and logistical reliability of Brigantes.
