3. Woolpower Lite Crewneck Unisex

Woolpower Lite introduces a material to meet the need for a thinner base layer: Woolpower Lite. The focus remains on functionality, with only as many seams as absolutely necessary. The material is very soft, form-fitting, and elastic – and it doesn’t smell. The new material still provides thermal protection, but crucially: thanks to the processed merino wool, it adapts to temperature and activity levels.

Woolpower Lite is made from ribbed knit fabric and consists of 80% merino wool (extra fine, 19.5 micrometers). The merino wool is blended with a synthetic polyamide fiber to produce stronger and more durable clothing. Of course, it is still "Made in Sweden."

Long-sleeved shirt with a small stand-up collar and a short zipper for ventilation. The turtleneck is made from fine merino wool using a circular knitting process. It has excellent insulation properties and keeps you warm even when wet and in extremely cold temperatures. These thicker garments are designed as a mid-layer to optimize heat insulation between the close-fitting functional underwear and the outer layer, which is worn for protection against wind and moisture. They are particularly useful in lower temperatures or during less intense activities. It is a knitted terry fabric, with one side being smooth and the other consisting of terry loops. The airy terry loops combined with the crimped structure of the wool create a jersey knit. 

5. Woolpower 200 Zip Turtleneck Unisex

It features a knitted terry fabric, with one side being smooth and the other made of terry loops. The airy terry loops combined with the crimped structure of the wool create a jersey knit that traps a significant amount of air, resulting in excellent insulation.

7. Woolpower 200 Crewneck Unisex

It provides outstanding warmth even when wet and in extremely cold temperatures.

8. Woolpower 200 T-shirt unisex

For the Tee 200, Woolpower uses Ullfrotté Original 200 g/m², the thinnest version of Ullfrotté. The terry-knitted material made from fine merino wool, a polyamide component, and naturally a lot of air is particularly durable. The airy terry loops combined with the crimped structure of the wool fibers create a jersey knit that traps a significant amount of air, resulting in excellent insulation properties. Wool is the functional material from nature. So far, no one has succeeded in artificially producing a fiber with such fantastic properties as wool. Wool is self-cleaning to a certain extent and does not smell unpleasant even when the body sweats. Since wool fibers can absorb up to 30 percent of their own weight in moisture without feeling damp, the absorption of moisture generates heat, allowing the Woolpower underwear to keep you warm even when wet.
