Woolpower Ullfrotté Original 400 grams fabric

The Woolpower 400 is a fabric that is used when the weather is colder and you don't have to move that much. Ullfrotté is a fabric that Woolpower has developed itself. It is a mix of merino wool and polyamide. Due to the special way of knitting, where one side of the fabric is flat and the other side consists of loops, this material retains a lot of air and therefore heat. The fabric absorbs moisture and sweat from the body and transports it to the outside of the fabric. This keeps your body warm. This also works the other way; when it is hot outside, the body is kept cool by the fabric. Wool does not absorb odors, so the clothes do not retain the sweat smell. Woolpower Ullfrotté 400 is made of 62% merino wool, 35% polyamide and 3% elastane.

The clothing is machine washable at 60 degrees and can be tumble dried. 

About Woolpower

Woolpower is a Swedish brand of thermal clothing and thermal underwear. The Swedish family business was founded in 1972 and has always specialised in manufacturing high-quality warm underwear. Wool has always been the main ingredient. The wool comes from merino sheep that graze in the Argentine part of Patagonia and Uruguay. All Woolpower products are made in Östersund, Jämtland.

The idea behind Woolpower is that it is not the thermal clothing that keeps you warm, but your own body. The thermal clothing has a unique structure that creates a layer of air between the body and the clothing. This optimally retains body heat.

Woolpower uses only mulesing-free wool and produces everything locally. The factories run on 100% renewable energy and waste material is reused for seat pads and insoles. Woolpower is certified according to OEKO-TEX and ISO standards, which guarantees high environmental standards. Want to know more about this supplier? Take a look at the Woolpower page.
