The invention

It isn’t just the wool that makes the difference. It’s the way we knit it.

The story of Brit and Eilif Lyngstad – knitted with air and love.

LYNGSTAD, 1994

It started because Eilif was cold

Eilif ran the farm at Lyngstad, and day after day he came home wet and cold from the forest and the farm work. Brit was a trained garment technician and had knitted all her life. She tried a new way of knitting, with far more small air pockets in the stitch.

Eilif put on the sweater, and he stopped being cold. Word spread from farm to farm, and in 1994 Brit borrowed a million kroner, bought a larger knitting machine in Switzerland and started production in the basement of the prayer house.

How the knitting method works

Wool alone isn’t the whole explanation. What insulates is the still air held in the knit – and Brit’s method builds a lot of it in.

    Air knitted into every stitch

    SINTEF described the knit as “a thick and open structure” with “a lot of air between the fibres”.

    The air holds the warmth

    Your body heat stays in the air pockets, even when you take a break. SINTEF found that the insulation follows the amount of air in the knit.

    The wool does the rest

    Wool can absorb a lot of moisture without feeling wet, so you stay warm when you stop after being active.

Body heatThe warmth from your body heats the air in the stitches.
Air in the stitchesStill air insulates well – that is why the knit holds the warmth.
MoistureThe wool absorbs moisture without feeling wet.

Two layers for the coldest days

SINTEF: Feltutprøving av LANULLVA undertøy på Svalbard 1995

SVALBARD, MARCH 1995

Tested by SINTEF at minus 23 degrees

Workers heading to Svalbard began ordering base layers from Brit, and she wanted to know whether what she had seen held up. In March 1995, SINTEF tested the base layer in the climate chamber in Trondheim, with test subjects alternating between hard work and rest. The conclusion was that the base layer “therefore appears to work well in conditions with varying work and rest in cold surroundings”.

The same week it was tried on Svalbard: three hours on a snowmobile at minus 23 degrees, with Lanullva as the only base layer under the suit. SINTEF called the results “very encouraging”.

“I’m 100% sure it was Lanullva that saved my toes.”

“Another very positive effect was that the base layer kept my body warm during rest breaks too. I didn’t get cold during the breaks.”
