The Havbris Half Zip is the light layer. Thin, soft merino wool you wear on its own on mild days or next to the skin under a sweater when it’s cold. You open the zip at the neck on the uphill and close it when you stand still.
The top is knitted using Brit’s knitting method – air knitted into every stitch, which keeps you warm. Brit Vinje Lyngstad invented the method in Lyngstad in 1994, because Eilif came home wet and cold from the forest and farm. The method was tested by SINTEF in 1995, including on Svalbard at −23 °C. Wool can absorb a lot of moisture without feeling wet, so you stay warm even when you stop after being active.
“Soft and just warm enough” – Anne M.B.
- Soft merino wool that many customers tell us doesn’t itch – even right against the skin.
- On the coldest days: Havbris next to the skin, Hustadvika on top
- 100% merino wool. The wool is RWS-certified, with requirements for animal welfare and traceability throughout the value chain.

It’s the air that keeps you warm
It isn’t just the wool that makes the difference. It’s the way we knit it.
Grandmother’s invention
Eilif came home cold and sweaty from working on the farm at Lyngstad. In 1994, Brit Vinje Lyngstad invented a knitting method with air knitted into every stitch – and Eilif stopped being cold. The following year, SINTEF tested the method on Svalbard.
- 1994Invented at Lyngstad
Brit knits the first sweater for Eilif.
- 1995Tested by SINTEF
Field-tested on Svalbard at −23 °C.
- 1996Svalbard, −50 °C
Worn by Scott Johnson, Arctic Polar, on Svalbard in February 1996.
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.

- 1Air knitted into every stitch
SINTEF described the knit as “a thick and open structure” with “a lot of air between the fibres”.
- 2The 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.
- 3The wool does the rest
Wool can absorb a lot of moisture without feeling wet, so you stay warm when you stop after being active.
Inside the knit
Two layers for the coldest days
Havbris next to the skin and Hustadvika on top. Two layers with air in the stitch, made to be worn together when it gets really cold.
