Ullfrotté Original Store

Ullfrotté Original was first developed by Woolpower AB in Östersund, Sweden during the early 1970’s in collaboration with the Swedish military. The result: a garment providing superior insulation and effective moisture management.

Our blend of fine Merino wool, synthetics, and air creates a supergarment that balances durability with raw function.

Intended to be worn directly next to skin, Ullfrotté Original’s unique terry-loop design with loose-knit wool fibers optimizes heat retention while effectively managing overall thermal comfort.

 It’s All in the Loops…

– Ullfrotté Original –

Ullfrotté Original is knit with a smooth outer synthetic layer, and a soft terry loop inner lining. The lofty terry loops on the inside, coupled with the natural crimp of Merino wool fibers, create a garment capable of trapping warm air circulating just above the outer layer of skin.

The permeable nature of Ullfrotté Original material allows moisture to be transported away from the body. As the body heats up, perspiration is released and water vapor accumulates inside your clothing. The terry loop design facilitates the process of trapping body heat while simultaneously releasing moisture.

Merino wool is naturally delicate. A pure wool garment therefore
does not lend itself to optimal wear resistance. In order to achieve
maximum durability, we created Ullfrotté: a Merino and synthetic
blend that offers increased strength, memory, and elasticity. Thus,
an ultra-resilient, comfortable garment is born.
