2-ply
Almost all of the traditional Icelandic wool sweaters that Alafoss offers are knitting with 2-ply plötulopi yarn. Icelandic plötulopi (plotulopi = unspun plates) – 100% new wool yarn. Each plate is about 100-110 g (3.5 oz) approx. 300 m (328yd).

Icelandic wool sweaters are valued for their beautiful designs and color combinations, and for the protection they provide against the elements. Not only do they have fun color patterns, but the wool fibers offer remarkable protection against both cold and wet weather.

Lopi (Icelandic: [ˈlɔːpɪ]) is knitting wool made from the fleece of Icelandic sheep. The fleece is made up of two layers, each with a different kind of wool. The wet-resistant outer coat contains long, coarse fibres, while the insulating layer beneath consists of soft, short fibres.

Soak it with Hair Conditioner – if you don’t have the patience to wait for it to soften over time, you can try soaking the wool. Many people said they were able to soften their wool by soaking the wool twice. The first time in lukewarm water and the second time with a high-quality hair conditioner.

Unlike other typical wools produced in other parts of the world, Icelandic wool stands out. However, this doesn’t mean that it itches more or itches less than other wool. People have been wearing these products for centuries because they are water repellent and warm too.

There aren’t a lot of posts or resources that will tell you what Lett-Lopi (Icelandic yarn) actually feels like when you wear it. And when you feel it on the skein you might be afraid to give it a try because it’s very scratchy. It’s not a plush ball of softness of the sort we next-generation knitters trend towards.

It was rainy and cold, but one thing colored the streets of Reykjavík: The lopapeysa (literally: “lopi wool sweater”), which so many Icelanders wear. One glance and we were sold on these beautiful Icelandic sweaters.

The cost depends on two major factors. Those two are the location in Iceland and whether or not you are willing to buy a used one. The used ones start at about 8,000 ISK which is dollars comes down to $65 (2019) but they do go up to about 20,000 ISK ($165) when bought new in downtown Reykjavík.

Lopi softens with washing and wearing—give your finished garment a bath in warm water with a little lanolin soap so the fibers will relax and soften. I use the brand Eucalan, which is available at my grocery store as well as at many local yarn shops, but there are several others.

Our wool sweaters are hand knitted from Icelandic wool yarn. The sweaters are called Icelandic wool sweaters or Lopapeysa.

The Icelandic lopi sweater or Icelandic sweater lopapeysa for women are traditionally decorated with classic patterns and these wool products are heavy wool sweaters and also called Iceland cardigan, Icelandic cardigan, Iceland wool sweater, Icelandic wool jumper and many other names but are first and foremost Icelandic wool sweaters for women.

Since Plötulopi is an unspun yarn, it is fragile to work with; however, due to the length of its fibres, it knits into a sweater that is both sturdy and soft.
