Long Johns 400 Woolpower tights

The Long Johns 400 Woolpower tights are a garment made of merino wool with a density of 400 g/m² which gives it a very good quality of thermal insulation to "face" the great cold.
 
This garment from the Ullfrotté range is woven in Sweden in the city of Östersund. Since its creation in 1972, Woolpower has not stopped releasing models of warm clothes from unique weaving techniques.
This garment is made from a Woolpower proprietary material called Ullfrotté Original. This is made of a mixture of 2/3 fine merino wool and 1/3 synthetic fibers. It features a unique knit structure with highly airy wool loops, insulating heat and wicking sweat away from the skin.
The Ullfrotté Original material benefits from all the properties of merino wool (warmth, breathable, anti-odour) and synthetic material which guarantees significant solidity to the garment.

To ensure quality, each item of clothing is sewn by a single seamstress who checks the product herself and affixes a label with her name.
This garment can be cleaned at 60°C if necessary.

Exceptional in terms of insulation, the Long Johns 400 Woolpower boxer shorts are ideal for all activities practiced in extreme cold when the temperature is negative (outdoor sports, outdoor recreation, outdoor work...).

Tips for Choosing Woolpower Underwear:

• First coats: 200 gsm

Les sous-vêtements avec une fibre de densité 200 g/m² sont les vêtements les plus fins. Ils sont conçus pour être portés directement sur la peau, ce qui permet une bonne évacuation de l’humidité.
By being used close to the body, their thermal effect combines perfectly with the function of eliminating perspiration.
Ces sous-vêtements fins sont idéals pour des températures allant de +10 °C à -20 °C, en accord avec l’activité pratiquée.
The merino wool/polyamide knit has a smooth surface on the outside, and a terry cloth on the inside.
Composition: 60% merino wool, 25% polyester, 13% polyamide, 2% elastane

• Middle layers: 400-600 g/m²

Underwear with a fiber density of 400-600 g/m² is thicker and is worn as an intermediate layer.
They improve the thermal insulation between the base layer and the outer, water-repellent and windproof protective layer. Intermediate garments are generally used when the cold is more severe, and during more static activities.
