All Baselayers

Base layers – merino wool base layers for women, men and children

The base layers collection brings together North Outdoor's entire range of merino wool base layers – from the thin Active base layer to the thicker Intense Pro and Arctic series. Here you'll find the right base layer for every situation: everyday life, the outdoors, sport and the most demanding winter conditions.

A merino wool base layer is a year-round choice that works as a warming base layer in winter and a moisture-wicking, close-fitting garment in summer. The natural material never feels clammy, stays fresh for a long time and suits even sensitive skin.

Different weights for different uses

The range includes the thin All day base layer, the sport-ready Active series, the thicker Intense Pro and the warmest Arctic base layer. Choose the weight to match the activity and temperature.

For the whole family

The base layer range covers base layers for women, men and children. There's a base layer in the right size and the right warmth for everyone.

Works in summer too

Merino wool is an excellent material for summer use as well. A thin merino base layer works as UV protection and a moisture-managing layer even in hot conditions.

Explore the full base layer range

Find the merino wool base layers that suit you or your family. A quality base layer is a long-lasting investment that pays for itself over years of active use.
