Arctic – the warmest merino base layer for northern frost
The Arctic collection is North Outdoor's warmest merino wool range. It is designed for situations where warmth is needed most – freezing conditions, long spells outdoors and situations where ordinary base layers aren't enough. Arctic pieces are made from an especially thick merino knit that insulates heat exceptionally well.
Despite its thickness, Arctic is still a natural merino wool product: it breathes, wicks moisture away from the skin and stays antibacterial. An Arctic base layer can be worn directly against the skin or as a mid layer in especially cold conditions.

The best choice for freezing weather
The Arctic range's thicker merino knit provides thermal insulation that thinner base layers can't match. It's an ideal choice for winter trekking, ski trips and other situations where the cold has to stay out.
Worn on the skin or as a mid layer
Arctic pieces work both as thick base layers and as warming mid layers. Their versatility across layering situations makes them a great choice for cold northern climates.
The benefits of merino wool remain
Even though Arctic is the thickest merino wool in the range, it keeps all of merino's key properties: breathability, moisture management and natural antibacterial performance. It's a durable, reliable material for the most demanding winter conditions.
